84 48 lcd module arduino made in china

I tried loading the zip library for the UVmeter as it came from the site, but IDE was having none of it, the error reads (Specified folder/zip file does not contain a valid library) so I unzipped it (reluctantly) and then loaded the .ino file and 2 .c files that opened in separate tabs . The LCD zip was added to the IDE as instructed without a flaw, and when i clicked on it, the IDE showed:

In terms of my hardware, the only thing that hasn"t showed signs of life yet is the LCD_5110 i just bought from somewhere in canada, it looks well, but i did not try to check it on its own ( not that i could have done it before you guys told me how to load the software), but i saw a backlight flash when this program loaded, just for a second and again if i hit the white reset button in the UNO. The Arduino Uno seems to work, we ran a few of the simple projects in the starter kit and had a couple sensors tested alone. I had tested the SMAKN UVM-30A sensor alone before with simple code from electropeak,

I had a project that needed some live data display, and looking for the cheapest low-power solution for our loggers lead me to the Nokia 5110 LCD. Once you get the backlight current under control, you can power the entire display from a digital pin, and if you use shiftout for soft SPI you can then get rid of the Reset and CS control lines. This brings the display down to any four wires you can spare on your build (incl. the power pin) and a ground line. This is much more manageable than what you see with the standard hookup guides if your mc is I/O limited like our pro-mini based loggers:

This LCD (I have the old-old kind) is absolutely my favorite. Yes, it has a board-to-glass connector that ranges from bad to abysmal, but it offers such a simple interface and so many pixels for so little money (obviously less if you buy only the panel.) Here are some clever things I"ve discovered:

Will fully operate on as little as 2.0V. That"s power (Vdd) and i/o. It can be driven at 2MHz at these speeds; in fact, the LCD will work at even lower voltages but the contrast fades quickly and your microcontroller will likely approach its lower voltage limit too.

The LCD will work with the chip-select pin (SCE) tied to ground. This means that if it"s the only device on the SPI bus, don"t bother framing the i/o with a chip-select pin. If the bus is shared, frame the entire transaction, not every individual byte you send to the LCD. Interestingly, the display also seems to work fine with a floating Vdd pin - it must draw sufficient power just from i/o via clamping diodes; not surprising when you consider how low-power it is.

The Vout pin: Looks like you don"t have to worry about it on this product, but the bare LCD will generate positive 6-9V on that pin. This wasn"t totally clear to me from reading the datasheet.

(5) If you are using a PIC to run ths thing, and using the PIC"s USART or EUSART in a synchronous mode, be sure to note that the LCD controller expects the MSBit of each byte to be transmitted first on the serial line. The PIC 18F EUSART transmits the LSBit first. For now, I have lots of extra code space, so I"ve wasted a 256-byte section on a lookup table that reverses the bits in a byte. This way, I just write my initialization code normally, and I have a TransmitCommandByte() function that looks up every byte it sends so I don"t have to think about that.

Thank you! I"m not quite sure I do want an LCD yet, to be honest, I"m just considering the different options available. I"ll check out the Sharp component, thanks!

Advice for others: It took me quite a while to get this working on an ARM Cortex. Since there is no way to read from the LCD, it is very hard to know if SPI is working without doing everything perfectly. SO:

The problem I had was solid black display screen. No matter the combination of bias and contrast values that I set. The unit wasn"t totally defective, because under a strong lamp light you could see the display trying to show the letters and pictures that are in the tutorial for Arduino that I got from SFE.

If the LCD module is soldered to another board and the two top screws installed and tightened carefully to pull the bow out of the module it seems to prevent (or solve) the problem.

The Arduino code works fine for me, but I can"t make any thing work with Pic. I found this code at http://www.sunbizhosting.com/~spiral/ , but can"t figure out what I"m doing wrong.

I"m using voltage dividers to supply 3V in the inputs of the LCD, because of the Arduino works in 5V. LCD Vcc and LED are powered from the 3.3V output of the Arduino. The LCD only displayed something when I used: R1=470K,R2=820K. I have tried several values to obtain 3V, but the LCD showed nothing. I don"t understand that.

I"m interfacing this LCD with ATMEGA 32. Its been more than a week that I"ve been trying to get it right. All I get is the LED dimming effect. Here is my initialization code..CE=1;

I have a similar board made by mib-instruments and bought from ebay years ago. It has been my standard spi test tool because it"s so easy to work with. http://www.ebay.com/itm/Nokia-5110-LCD-84x84-dot-martix-backlight-PCB-RED-/320684678723 (specs http://i1119.photobucket.com/albums/k636/mib_instruments/diy/LCDC2A0SPEC.jpg)

I wanted another one so i bought the sparkfun item but it doesn"t quite work: it flickers and blackens occasionally but my graphic never shows up. Is there a bulletproof arduino sketch I could use to test it?

I almost have it working satisfactorily but I find that the bottom 1/5th of the screen does not function correctly. Sometimes it has some random blocks that are black, most of the time it is blank. I am not sure what would cause this. Is it safe to assume it is a defect on this module?

These LCD"s need cleaning. I have an average failure rate of about 15-20% on delivery. The most common problem is that the contrast is too high, and there"s constant flickering / changing of contrast compared to the other 80% of them.

The solution is fairly simple, unclip the LCD from it"s board and clean the pads on the PCB with 99% IPA. Then remove the lcd back plate and contact bar. Sometimes the contact bar is stuck fairly well to the glass, peel off carefully. Clean the contacts on the LCD glass with IPA, if any residue from the contacts is left on, rub it off carefully with IPA / tissue.

I love this little display! I wanted to be able to create images for it but nothing I saw did exactly what I wanted. So I wrote a processing sketch that creates 84x48 squares on the screen and allows you to click to turn them on or off. Also has buttons to invert, move up/down/left/right, and flip horizontally/vertically. Then, it saves the hex data to a text file to copy to your code. You can also load an image (any size, any colors) and it will scale it, convert to b/w, then put it in the rest of the program so that you can alter the pixels or move it. It isn"t perfect for every occasion but I"ve found it useful and I hope others might too. It is heavily commented so it should be easy to figure things out and change them if you want something different. http://thewanderingengineer.com/2014/07/12/nokia-5110-screen-photo-to-bitmap-converter/

Never mind, I had no problem running it at 5V directly from the Arduino with the contrast value bumped up to 45 or above. With 10K ohm resistors on the control lines as shown in the sample hookup, I get a blank screen. Also removing the backslash from the sample code got garbage characters, so I left it in.

Anyone taken these things apart yet? You know the flexible rectangular blocky thing that connects the contact pad on the board to the LCD itself? What are these called?

Got mine running last night and found two problems with the code, one of which was the backslash a couple of others have already noted. Second was that the LCDCharacter() writes two blank vertical lines, one before the character and a second after, when only one is needed. Without the extra blank you get at least one additional character on each line. I"ll probably also move the ASCII font table to PROGMEM space to save on RAM and then start to work on some big digits for a clock.

I"m using this LCD for a large Arduino UNO project, but I"m running out of SRAM memory space. I was wondering if I used PROGMEM on the LCD ASCII array if that would help. If so, does anyone know what the right code for this would be? After looking through a lot of PROGMEM examples, I"m not advance enough to really grasp everything that"s going on. Any help you can give would be a great help. Thanks in advance!

I used one of these LCDs with an Arduino to display GPS information. I wrote a few functions that can display large numbers (28 px high) if anyone is interested, this lets me display speed, heading etc. A writeup of my project is here: http://mechinations.wordpress.com/2014/04/07/gps-sailing/

These are great displays. I ran into a problem using them with the nRF24L01+ radio transciever, which requires the use of the SPI bus. If one attaches both the radio and the display MOSI and SCK pins to pins 13 and 11 as instructed in the hookup guide, the SPI traffic of the other device (in this case the nRF24L01+ radio) will prevent the display from functioning. The easy solution is to move the Nokia 5110 MOSI and SCK pins to any other digital pin. This should be made clear in the hookup guide, where it says there is no choice but to use the hardware SPI pins for the display. I found out that is not true at all. I hope his helps others with the same problem. Despite the occasional bad display these carry much more information that the comparably prices 16 x 2 LCD and use fewer pins too boot. What a deal!

This is a great display for the money, certainly the best bang for the buck of you can live with B&W and lower res graphics. I have a lcd driver for Arduino I will post on http://www.marchdvd.com/5110 so take a look there it draws text aligned on pixels boundaries of 8 and draws lines and has invert video options.

I just started messing around with this LCD using a STM32F103 microcontroller running at 72MHz... it works great. The only problem I had, and I suspect others might have if they are using fast processors, is that you have to deliberately introduce the setup and hold time delays on the DC pin... if you don"t you will get spurious pixels written to the display. I used a delay of 10uS, although the spec says 100nS is fine.

Just a heads up to anyone trying to run the Arduino example. Make sure you plug Vcc into the 3.3V output on the arduino board. I also had to change the line

Can someone help me edit the code in the arduino example to display readings from a sensor, I"ve looked through all of the links and searched through the Internet but I couldn"t find an example anywhere, it would really help me if someone could tell me how to do this.

Has someone already been able to get this display to work with an Arduino Due? For some reason I cannot get it to work while it does work perfectly on my Mega. Any ideas why it may not work?

Added a driver for this display to the object-oriented arduino platform; Cosa. Please find example code at https://github.com/mikaelpatel/Cosa/blob/master/examples/Drivers/CosaPCD8544/CosaPCD8544.ino and source code at https://github.com/mikaelpatel/Cosa/blob/master/Cosa/IOStream/Driver/PCD8544.hh.

I just spent the last couple hours struggling with this LCD because of something very stupid of me. I was using an atmega328p in AVR-GCC and using hardware SPI. Thinking i didn"t need MISO I hooked it to DC. The LCD worked absolutely fine until I tried to set the x and y position in the ram. It started acting weird every time I tried it. Finally I put dc to another pin and BAM NO PROBLEMS. Looking back I feel pretty stupid but hopefully this post will save someone else the same mistake. Other than that great LCD for my projects

The Energia folks have an example program for this LCD and the TI Launchpad written using their Arduino style tooling. I"ve updated their example and added the ability to report back the temperature over a UART. It is a very simple hardware setup since both systems are 3.3v. http://joe.blog.freemansoft.com/2012/08/digital-thermometer-with-ti-lanchpad.html

2) I"m really struggling to find unformation on using this display with the Arduino. The example (pcdtest.pde) provided with the Adafruit libraries (Adafruit_PCD8544 and Adafruit_GFX) won"t even compile and the only library I have found that I can make any sense of using is the PCD8544 library from Google (http://code.google.com/p/pcd8544/downloads/detail?name=PCD8544-1.4.zip) and I can"t really uderstand how to do graphics with that.

I tried using the "LCDAssistant" package to create a logo from a graphic that I resized to a b&w jpg of 84x48 but every byte generated was 0x00 so that was not right. I tried fiddling with the settings (flying blind) but still got nowhere - does anybody know the settings for LCDAssistant and this display and has used it successfully?

One of the things that I test regularly is a commercial item that features a 16x4 (HD44780) display. Currently I have a 20x4 on a flying lead that I plug in to determine if a display failure is down the lcd display or the main board.

I am using arduino example and while i am getting proper images and text i also get some odd horizontal flickering. It looks like several horizantal lines across the screen on the background with image/text on foreground. I tried switching to only use digital pins on my arduino leonardo but i still see this behaviour. Any ideas?

Might I suggest you (SFE) source some of the Electronic Assembly"s LCD Dog-S series. I think they would be a step up from these at a reduced price. I don"t think that they website is up to date, but their part number is LED39x41-GR.

I finally got around to running this LCD on my 3310 PCB. It is working fine with one minor problem. The SF 3310 display hides to first line of bytes for some reason and I had to offset everything to compensate. The 5110 doesn"t do this as behaves as expected. I haven"t heard anyone else report this so maybe my initialization code is different.

Using a 3V source, my LCD often worked OK using bias 0x14 like the other examples, but sometimes it would appear gray and faded. The fading would lessen if I touched the panel lightly with my hand for a few seconds, then let go, so maybe it"s a temperature-dependent thing?

0x14 is not 1:48 bias. If you read the datasheet on the top of page 16, 0x14 corresponds to a bias of 1:40/1:34. If you want 1:48 bias as the comment says, use 0x13. The 0x15 value I"m using corresponds to 1:24 bias.

Ack! After two days of working nicely with 0x15 bias, I reset the board today, and the LCD appeared way over-dark. I changed the bias back to 0x14 and it looks perfect. What the heck?! I think there must be some temperature-sensing or temperature-dependence going on, so the same init values may produce good-looking results one day but not the next.

Does anyone know whether this can be stripped of its backing so it can be used in transmission? I would love to use this as a modulator for a laser beam. Or if someone knows a similarly cheap transmission LCD that would be fine too.

For those of the arduino persuasion, I wrapped some simple methods up in a library based on this arduino page http://www.arduino.cc/playground/Code/PCD8544.

Stuck. Blank LCD. Added 0x20, changed Vop to 0xB3. Guessing connections may be the issue? 3.3v for LED and VCC. GND to GND. Remainder connected to Arduino via voltage dividers. What am I doing wrong?

This is a great little lcd. When I first wired it up, the backlight was shorted (accidentally) against my 5v rail, so i got some magic smoke, and burnt to LEDs but it re-soldered the offending joints and it works very well now. Something to note: the refresh and write times are much, much slower if you use 5 volt logic. I stuck in a logic level converter and it ran at least 5x faster.

You can also use FastLCD to convert your bitmaps - google it. It outputs BASIC code, but you just search and replace &h to 0x and you"re grand. It has the added advantage of being an editor for touching up output.

I recently obtained a virtually identical LCD from a Nokia 5160, and although its backlight LEDs are green, not white and conversely use different voltages, I had success hooking up the LEDs" Vcc pin to a PWM capable pin on the microcontroller, allowing me to control backlight intensity (I didn"t need a current limiting resistor for this either, but adding one will help reduce current drain on the controller).

Seems like the PCD8544 library does it"s own SPI bit managing and it really doesn"t like me using the SD library (also talks SPI) at the same time. I"ve made sure I"ve got all the SPI pins matching for both libraries (MISO, MOSI, Clock are the same and each device has it"s own Select), but it looks like the SD.begin() call just breaks the SPI bus for the 5110 and it becomes non-responsive. The LCD works just fine if I don"t initialize the SD library and the SD card works fine if I do initialize the SD card.

I"m pretty sure I tracked down the problem- the PCD8544 library uses software SPI while the SD library uses hardware SPI and I"m pretty sure the Arduino can"t do both over the same SPI clock/miso/mosi pins. Anyone know if this LCD will work with hardware SPI?

I"ve had issues with the LCD not showing anything intermittently. You got to make sure that all the connections are secure, and for the reset pulse, be sure to have a delay that"s 30-50 milliseconds long.

As much as I love SFE products and will continue to order from them, this is one product I would not recommend. The connection between the LCD unit itself and the carrier board is via those rubber polymer connectors. All the planets must line up properly for them to work. In this case, the carrier board was warped preventing the connection from working. You will find other such remarks in the comments area.

I"ve followed the linked-to Arduino example and I get nothing on the display. Should it just work without any other components? The link mentions a possible cap on VOUT but there"s no such pin. Googling has suggested my Duemilanove"s digital pins will be @5V but I need 3.3V?

Don"t do this. Each divider will be burning 20x the entire amount of current that the display needs to function, and the whole assembly will waste 100x the LCD"s needed power and many, many times more than even the atmega needs to run at full speed. This will kill battery life.

Either use higher resistor values, n-mosfets for level conversion (see this Sparkfun BOB for an example), or drive the whole system on 2.0V - 3.3V (don"t know how easy that is with an Arduino.)

Hi, I just bought this wonderful LCD but I"m having huge huge problems connecting it..could anyone please point me in the right direction? Since there are pins that aren"t metioned in the code, for example the 6 - DNK(MOSI)...

Does anyone know the diode rating and package size, also does anyone know where to get the rubber ferroius connector behind the LCD mine is defective. Has anyone come into issues with the breadboard the LCD is connected to, a few aren"t working for me.

Yes, we have noticed that the PCB was bowing and as a result the LCD now only works when we press down on the metal strip at the top. I hope that only a small number of these LCDs have this problem. We"re expecting a shipment to arrive today, I will be running more tests.

Edit: After leaving glue to dry overnight, LCD simply does not turn on anymore. All the connections are good, but absolutely nothing shows on the LCD now at all. Only the LEDs come on.

Did you get either of the LCDs to display anything, at any time? Is it possible that the connections were OK, but you were not initializing or driving them correctly? Or did they start to work at one point, and then fail at some later point?

Note that the backlight LED"s are soldered onto the breakout board, and have nothing to do with the circuitry of the controller and LCD. So just because the backlights are shining doesn"t tell you anything about the operability of the LCD itself.

It depends on the code that you are using to control the LCD. If you are using the Arduino example above, the pins are defined in the beginning of the code.

FWIW I have connected this LCD with a 5V power supply to a 5V Arduino board with no level conversion and it worked. Presumably this may reduce the lifetime of the LCD.

I am attempting to use this with a Duemilanove (ATmega328). Up til now, I have been powering it with the 3.3V line, including the LED. The datasheet for the LDC claims: "VDDmax = 5 V if LCD supply voltage is internally generated (voltage generator enabled)." The logic levels should be kept from 2.7V to 3.3V. Since the Duemilanove uses 5V logic levels, I am using a simple voltage divider on the communication line with no issues.

The maximum logic value of 3.3 volts made me cautious of driving the LCDs at the native 5 volts of my Teensy AVR. That said, running purely off 5 volts seems to do no harm to the LCD.

For those interested, I have taken a few measurements of the current draw of the LED backlight of my LCD. As I said earlier, powering the LED with 5V external has caused permanent damage to one, perhaps two of the four LEDs. So, use the following graph at your own risk.

Is there any more documentation available for the additions to the LCD? For example, the datasheet has no information (that I could find, at least) on the LED. Everything seems fine on 3.3V, but what is the current limit on the LED? (note: if it wasn"t for work, I would just mess around with it myself.)

Here is a PicBasic Pro example for the 3310, which should be compatible with the 5110. http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD

If anyone doesn"t have experience with this LCD, take a peak at the Arduino example link above to see just how easy it is to use. If you use plain C on your AVRs, I have sample code on http://tinkerish.com.

The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended for as a cell phone screen. This one is mounted on an easy to solder PCB.

It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

These 84 by 48 pixel black and white LCDs are what you might be found in an old Nokia 3310. They’re not flash, and they don’t have a lot of display real-estate. But they are easy to control. If you’re looking to step up your project’s with user interface (UI) game from simple displays or LEDs, this graphic LCD is a good place to start.

before we display our first image and real time sensor values on this LCD, let look at the pinout for this LCD, To interface with Arduino and power the graphic LCD, there are two, parallel 8-pin headers above and below it, flipping the board over, you will find the labels for each of the pins.

To supply voltages on the LCD,the most important supply voltage — VCC — which  supplies the logic circuits inside the LCD. The datasheet sates this should be between 2.7 and 3.3v. in normal state, the LCD will consume about 6 or 7mA

3.3V  is required for LED back-lights on the board. if you were to remove the LCD from the PCB (not that you should, or need to), you’d see that these are back-lights in their simplest form- four white LEDs spaced around the edges of the board. You may also notice that  there aren’t connected to any current limiting resistors.

Built into this LCD is a Philips PCD8544 display controller, which converts the massive parallel interface of the raw LCD to a more convenient serial one. The PCD8544 is controlled through a synchronous serial interface similar to SPI. there are clock(CLK) and data(DIN) input lines, and an active-low chip select(SCE) input as well On top of those three serial lines, there another input -DC-which tells the display whether the data it’s receiving is a command or displayable data.

The PCD8544 LCD controller has flexible yet complex drivers. Vast knowledge on memory addressing is required in order to use the PCD8544 controller. Fortunately, Adafruit’s PCD8544 Nokia 5110 LCD library was written to hide away all the complexities so that we can issue simple commands to control the display.

Filter your search by typing ‘nokia’. There should be a couple entries. Look for Adafruit PCD8544 Nokia 5110 LCD library. Click on that entry, and then select Install.

This will give you complete understanding about how to use the Nokia 5110 LCD display and can serve as the basis for more practical experiments and projects. Try the sketch out and then we will dissect it in some detail.

You should consider the display as a 3v3 display only, do not feed it 5v signalling, and absolutely do not put 5v on Vcc if you are using a 5v Arduino, you need to level-shift.

Depicted here is the general wiring required. As mentioned above if you are using a 5v Arduino you MUST level shift, there are many ways to accomplish the level shifting so it"s shown here as a "black box" insert your specific type of level shifting arrangement as necessary (or use a 3.3v Arduino).

Notice that there is a 330Ω Resistor shown on the BL (Backlight) pin, you can adjust this resistor (or use a potentiometer, or connected it to a PWM pin of your arduino or ...) as desired to get whatever backlight brightness you want (or not connect it at all to turn it off).

Upload the example to your Arduino and admire the beauty of your display. Try the other examples for more excitement and to learn how to control the display! It"s easy!

Adjust contrast - open the File > Examples > PCD8544_Simple > A01_ContrastHelper sketch, upload it, hopefully you will find a contrast level which suits. You can then put lcd.setContrast(xx); right after your lcd.begin() in your actual sketch.

Try pressing firmly in the center of the top metal section of the LCD. Underneath this is the "zebra strip" which presses against the PCB contacts, sometimes these don"t make a good connnection. If pressing helps, press it firmly then bend the tabs over a bit to hold it in place.

Still no go, and you are sure your wiring is OK, remove the LCD from the PCB (use a thin screwdriver to straighten and push the tabs through the holes), once removed you will see the contact points on the PCB hwhich you can swab with a cotton bud dipped in a solvent like acetone or methylated spirits. Looking at the back of the LCD you will see the "zebra strip", a short (about 1cm) strip of a (in the ones I have done, beige coloured) rubber type material, wipe that surface with your swab as well. Reassemble, and when doing so press it firmly to the PCB when bending the tabs to ensure a good strong contact is made (I use a quick-clamp).

In the previous tutorial I showed how to build a weather station using DHT11 and BMP180 with an Arduino. However, the project has a downside which is the power consumption of the 16X2 LCD. If we were building a battery powered project with the desire to last for several weeks and probably several months, like a weather station for instance, then we’ll have to replace the LCD keypad shield from the previous tutorials and go for something like the low powered Nokia 5110 84×84 LCD display. In this tutorial I will be showing you how to drive this display with the Arduino and thus build projects with longer battery life.

Since we are just going to drive the display we won’t be needing sensors for this tutorial, however we will need the components listed below which include the Nokia 5110 itself and we will show how to drive the display using an Arduino board.

The Nokia 5110 display is basically a graphic LCD display useful for a lot of applications. It was intended originally to be used as a screen for cell phones and was used in lots of mobile phones during the 90’s. This display uses a low powered CMOS LCD controller/driver PCD8544, which drives the graphic display of size 84×48. It is very cheap and costs about 3$. You can get one here.

The Nokia 5110 LCD can display text, graphics as well as bitmaps. When this display is fully lit, it draws about 10mA but with the backlight off, it draws as low as 0.4mA. The power consumed by this display is very low compared to that of the keypad LCD shield used in the previous tutorial. I will be using the Arduino Mega for this tutorial as usual and you can buy one here. You can also buy jumpers, breadboards and power bank which you will be needing for this tutorial.

Before we start writing the code for this project, first we need to download the 5110 LCD graph library that was made by rinky-dink electronics. The library does most of the heavy lifting and makes it easy for us o use the LCD. Click here to visit the download page and then download the LCD5110_graph zip file. When done, unzip the file to your preferred location and then rename the unzipped folder to something simple like “LCD5110”. Copy and paste this folder in your arduino library folder, then run your arduino IDE.

Click on the file, then on examples and then click on LCD5110. Since we are using the Arduino Mega, under the LCD5110 drop down click on Arduino (AVR) and the open up the LCD graph demo file.

In the code we only have to change a few things. we can see from the comment section above that the RST pin of the display was connected to pin 11 but in our case we connected this pin to pin 12 of the Arduino Mega. We also have to change the CS from pin 12 to 11.

The first line after the comment section, the LCD5110 library was included and after that a myGLCD object was created with the numbers being the pins to which the LCD is connected. The last two values in the myGLCD object is the RST and CS values which has been changed as explained initially.

with this done, we move to the setup function. In the setup function, the InitLCD method is used to initialize the display and this method takes in a parameter for the display contrast. The contrast value is between 0-127 and since we didn’t pass in any value the default value which is 70 will be used. Next, the setFont method is called which sets smallFont as the display font style is called and lastly, the randomSeed function which is used to initialize the random number generator using analogRead on an unconnected pin as a random input.

In the loop function, on the first line the screen buffer is cleared using the clrScr method. The drawBitmap method was used to draw the arduino logo and this logo is placed in the screen buffer when the method is called. The update method is used to copy the screen buffer to the screen then we give it a delay of 2 seconds before clearing the screen buffer again.

Most of the functions used in the project have names that are self-explanatory like myGLCD.drawLine needs no explanation for instance as its clear the function draws a line.

Here is the full code for this project. Its an example from the Library named LCD5110_Graph_Demo and how to get to it has been described at the beginning of this section.

Arduino boards are available commercially from the official website or through authorized distributors.

Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards ("shields") or breadboards (for prototyping) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the Arduino language, inspired by the Processing language and used with a modified version of the Processing IDE. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go.

The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea, Italy,sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

The name Arduino comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet. The bar was named after Arduin of Ivrea, who was the margrave of the March of Ivrea and King of Italy from 1002 to 1014.

The Arduino project was started at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy.BASIC Stamp microcontroller at a cost of $50. In 2003 Hernando Barragán created the development platform Casey Reas. Casey Reas is known for co-creating, with Ben Fry, the Processing development platform. The project goal was to create simple, low cost tools for creating digital projects by non-engineers. The Wiring platform consisted of a printed circuit board (PCB) with an ATmega128 microcontroller, an IDE based on Processing and library functions to easily program the microcontroller.Arduino.

Following the completion of the platform, lighter and less expensive versions were distributed in the open-source community. It was estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced,

At the end of 2008, Gianluca Martino"s company, Smart Projects, registered the Arduino trademark in Italy and kept this a secret from the other co-founders for about two years. This was revealed when the Arduino company tried to register the trademark in other areas of the world (they originally registered only in the US), and discovered that it was already registered in Italy. Negotiations with Martino and his firm to bring the trademark under control of the original Arduino company failed. In 2014, Smart Projects began refusing to pay royalties. They then appointed a new CEO, Federico Musto, who renamed the company Arduino SRL and created the website arduino.org, copying the graphics and layout of the original arduino.cc. This resulted in a rift in the Arduino development team.

At the World Maker Faire in New York on 1 October 2016, Arduino LLC co-founder and CEO Massimo Banzi and Arduino SRL CEO Federico Musto announced the merger of the two companies.

In April 2017, Wired reported that Musto had "fabricated his academic record... On his company"s website, personal LinkedIn accounts, and even on Italian business documents, Musto was, until recently, listed as holding a PhD from the Massachusetts Institute of Technology. In some cases, his biography also claimed an MBA from New York University." Wired reported that neither university had any record of Musto"s attendance, and Musto later admitted in an interview with Wired that he had never earned those degrees.open source licenses, schematics, and code from the Arduino website, prompting scrutiny and outcry.

By 2017 Arduino AG owned many Arduino trademarks. In July 2017 BCMI, founded by Massimo Banzi, David Cuartielles, David Mellis and Tom Igoe, acquired Arduino AG and all the Arduino trademarks. Fabio Violante is the new CEO replacing Federico Musto, who no longer works for Arduino AG.

In October 2017, Arduino announced its partnership with ARM Holdings (ARM). The announcement said, in part, "ARM recognized independence as a core value of Arduino ... without any lock-in with the ARM architecture". Arduino intends to continue to work with all technology vendors and architectures.

Under Violante"s guidance, the company started growing again and releasing new designs. The Genuino trademark was dismissed and all products were branded again with the Arduino name. As of February 2020, the Arduino community included about 30 million active users based on the IDE downloads.

In August 2018, Arduino announced its new open source command line tool (arduino-cli), which can be used as a replacement of the IDE to program the boards from a shell.

Most Arduino boards consist of an Atmel 8-bit AVR microcontroller (ATmega8,ATmega328, ATmega1280, or ATmega2560) with varying amounts of flash memory, pins, and features.Arduino Due, based on the Atmel SAM3X8E was introduced in 2012.shields. Multiple and possibly stacked shields may be individually addressable via an I2C serial bus. Most boards include a 5 V linear regulator and a 16 MHz crystal oscillator or ceramic resonator. Some designs, such as the LilyPad,

Arduino microcontrollers are pre-programmed with a boot loader that simplifies uploading of programs to the on-chip flash memory. The default bootloader of the Arduino Uno is the Optiboot bootloader.RS-232 logic levels and transistor–transistor logic (TTL) level signals. Current Arduino boards are programmed via Universal Serial Bus (USB), implemented using USB-to-serial adapter chips such as the FTDI FT232. Some boards, such as later-model Uno boards, substitute the FTDI chip with a separate AVR chip containing USB-to-serial firmware, which is reprogrammable via its own ICSP header. Other variants, such as the Arduino Mini and the unofficial Boarduino, use a detachable USB-to-serial adapter board or cable, Bluetooth or other methods. When used with traditional microcontroller tools, instead of the Arduino IDE, standard AVR in-system programming (ISP) programming is used.

The Arduino board exposes most of the microcontroller"s I/O pins for use by other circuits. The Diecimila,Duemilanove,Unopulse-width modulated signals, and six analog inputs, which can also be used as six digital I/O pins. These pins are on the top of the board, via female 0.1-inch (2.54 mm) headers. Several plug-in application shields are also commercially available. The Arduino Nano, and Arduino-compatible Bare Bones Boardbreadboards.

Many Arduino-compatible and Arduino-derived boards exist. Some are functionally equivalent to an Arduino and can be used interchangeably. Many enhance the basic Arduino by adding output drivers, often for use in school-level education,

Arduino and Arduino-compatible boards use printed circuit expansion boards called shields, which plug into the normally supplied Arduino pin headers.3D printing and other applications, GNSS (satellite navigation), Ethernet, liquid crystal display (LCD), or breadboarding (prototyping). Several shields can also be made do it yourself (DIY).

Some shields offer stacking headers which allows multiple shields to be stacked on top of an Arduino board. Here, a prototyping shield is stacked on two Adafruit motor shield V2s.

A program for Arduino hardware may be written in any programming language with compilers that produce binary machine code for the target processor. Atmel provides a development environment for their 8-bit AVR and 32-bit ARM Cortex-M based microcontrollers: AVR Studio (older) and Atmel Studio (newer).

The Arduino integrated development environment (IDE) is a cross-platform application (for Microsoft Windows, macOS, and Linux) that is written in the Java programming language. It originated from the IDE for the languages brace matching, and syntax highlighting, and provides simple one-click mechanisms to compile and upload programs to an Arduino board. It also contains a message area, a text console, a toolbar with buttons for common functions and a hierarchy of operation menus. The source code for the IDE is released under the GNU General Public License, version 2.

The Arduino IDE supports the languages C and C++ using special rules of code structuring. The Arduino IDE supplies a software library from the Wiring project, which provides many common input and output procedures. User-written code only requires two basic functions, for starting the sketch and the main program loop, that are compiled and linked with a program stub main() into an executable cyclic executive program with the GNU toolchain, also included with the IDE distribution. The Arduino IDE employs the program avrdude to convert the executable code into a text file in hexadecimal encoding that is loaded into the Arduino board by a loader program in the board"s firmware.

From version 1.8.12, Arduino IDE windows compiler supports only Windows 7 or newer OS. On Windows Vista or older one gets "Unrecognized Win32 application" error when trying to verify/upload program. To run IDE on older machines, users can either use version 1.8.11, or copy "arduino-builder" executable from version 11 to their current install folder as it"s independent from IDE.

Most Arduino boards contain a light-emitting diode (LED) and a current-limiting resistor connected between pin 13 and ground, which is a convenient feature for many tests and program functions.Hello, World!, is "blink", which repeatedly blinks the on-board LED integrated into the Arduino board. This program uses the functions pinMode(), digitalWrite(), and delay(), which are provided by the internal libraries included in the IDE environment.

The open-source nature of the Arduino project has facilitated the publication of many free software libraries that other developers use to augment their projects.

Displaying information is one of the crucial steps in electronic projects. So if you want to display some custom characters or change the font size of the characters or even display some small graphical images, then Nokia 5110 LCD Module is the best option.

Nokia 5110 LCD Module, which is gaining much popularity among electronic enthusiasts and DIY project builders nowadays. The Nokia 5110 LCD was originally designed for use in Nokia Cell Phones, as you would have guessed (originally used in Nokia 5110 Mobile Phone. Hence, the name). In this tutorial, we’ll go over the entire process of connecting a Nokia 5110 to an Arduino.

Nokia 51110 LCD Display module developed for use with the iconic Nokia 5110/3316 mobile phone. It is capable of displaying alphanumeric characters, drawing lines, other shapes, and even displays a bitmap image. All this is possible only because of 84*48 monochrome. Nokia 51110 LCD Display module consists of an inbuilt PCD8544 interface IC which is easy to use with low-level microcontrollers. The PCD8544 is a low power CMOS LCD controller. Designed to drive a graphic display of 48 rows and 84 columns. This module communicates through the DSPI protocol, hence there is no need for more pins to communicate. This module has an inbuilt added library for Arduino which makes it ideal for novice programmers.

Nokia 5110 LCD module works on 3.3v and hence all pins are only 3.3 v tolerant. So in case if we are using a 5v microcontroller we need to use a logic level shifter. This level shifter acts like a potential divider to access the SPI pins of the display module. An on-chip generation of the LCD display and a bias voltage are inbuilt in the single-chip LCD display, as a result, minimum, external components and low power consumption is required.

The LCD in the Nokia 5110 comes with a backlight of different colours like green and blue. The bit pattern displays on 50 bytes of Graphic Display Data Ram (GDDR) on the PCD8544 LCD driver. Organized in 6 banks (0 to 5) with each bank containing 84 columns (0 to 83) that store 8 bits of data. Here each bit represents particular pixels on the screen which can programmatically turn ON or OFF.

Behind the wonderful Nokia 5110 LCD, there lies the PCD8544 LCD Controller from Phillips. It’s a single-chip solution for driving a 48-row, 84-column display. Internally, the PCD8544 Controller has a 504-byte SRAM for storing display data. The SRAM is divided into six banks (Banks 0–5), each of which can store 84 bytes of data. The maximum logic supply voltage is 3.3V. So, proper care must be taken while interfacing with the 5V logic level of Arduino.

The display module contains eight pins that are utilised to connect to Arduino through SPI. The Arduino board’s 3.3V pin is used to power the module. Because these modules operate on 3.3V logic, they do not deliver 5V to the displays’ Vcc pin. Even though the LCD works on 3.3V logic and Arduino on 5V logic, I directly attached the pin of the display to Arduino because it was the only way I could get the LCD to work properly. If needed, a voltage divider can be used to convert 5V to 3.3V, but it only works without the logic conversion. The connections are pretty simple and straight forward to make. Once you are done with the connections your set-up would look something like this shown below.

Before we begin coding, we must first download a few libraries in order to correctly execute the code. Go to Tools -> Manage Libraries in the Arduino IDE. Look for “PCD8544 Nokia” in the search box.

Select the “Adafruit PCD8544 Nokia 5110 LCD Library” library and click “Install.” “Adafruit GFX Library” is another library that we’ll need to install in order to display graphics on the LCD.

I hope all of you had become familiar with the Nokia 51110 LCD Display Module and its interfacing with the Arduino Board. In this blog, we just learned how to show bitmap pictures on an LCD using a simple project. I hope you find this post to be useful.
