It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

Think back to the pre-iPhone era, when the only time you touched your phone’s tiny black-and-white LCD screen was to wipe it clean. Back then, Nokia’s 3310 and 5110 cell phones used these tiny LCDs.

The PCD8544 controller’s on-chip LCD supply and bias voltage generation reduces power consumption, making it suitable for power-sensitive applications. The LCD normally consumes only 6 to 7 mA.

The backlight is made up of four LEDs spaced around the display’s edges. To change the LCD’s backlight, remove the LCD from the board by pushing the metal clips on the back side. You’ll notice four LEDs soldered around the display’s edges. Simply replace the LEDs with the desired color LEDs.

The PCD8544 LCD driver includes 504 bytes of Graphic Display Data RAM (GDDRAM) that stores the bit pattern to be displayed on the screen. This memory area is divided into 6 banks (from 0 to 5). Each bank has 84 columns/segments (from 0 to 83). And each column can store 8 bits of data (from 0 to 7). That certainly proves that we have:

The PCD8544 LCD controller has flexible but complex drivers. To use the PCD8544 controller, extensive knowledge of memory addressing is required. Fortunately, the Adafruit PCD8544 Nokia 5110 LCD library was written to hide the complexities of the PCD8544 controller, allowing us to control the display with simple commands.

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

This sketch will provide you with a thorough understanding of how to operate the Nokia 5110 LCD display and can serve as the foundation for more practical experiments and projects. Try out the sketch, and then we’ll go over it in detail.

In the setup function, we initialize the LCD object using the begin() function. We also set the contrast of the display using the setContrast(value) function, where value can range from 0 to 100. However, a value of 50-60 produces excellent results.

The final step is to use the display() command to instruct the library to bulk transfer the screen buffer to the PCD8544 controller’s internal memory and display the contents on the LCD.

Earlier in this tutorial, we used the setTextSize() function to set the font size. You can scale the font by passing any non-negative integer to this function.

The print() or println() functions can be used to display numbers on the LCD. Because an overloaded implementation of these functions accepts 32-bit unsigned int values, you can only display numbers ranging from 0 to 4,294,967,295.

Our last example shows how to draw bitmap images on the Nokia 5110 LCD display. This comes in handy when displaying things like logos, sprites, infographics, or icons.

The drawBitmap() function is used to display a bitmap image on the LCD. This function accepts six parameters: the top left corner X coordinate, the top left corner Y coordinate, the monochrome bitmap byte array, the bitmap width in pixels, the bitmap height in pixels, and color.

Once you have a bitmap, you must convert it into an array that the PCD8544 controller can understand. This can be accomplished in two ways: with image2cpp (online) or with LCD Assistant (offline).

There’s also a Windows application called LCD assistant that can turn your bitmap image into a data array. It is not as powerful as image2cpp, but it is still widely used by hobbyists.

This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on the LCD: static text, and scroll long messages. You can also use this guide with the ESP8266.

Additionally, it comes with a built-in potentiometer you can use to adjust the contrast between the background and the characters on the LCD. On a “regular” LCD you need to add a potentiometer to the circuit to adjust the contrast.

Before displaying text on the LCD, you need to find the LCD I2C address. With the LCD properly wired to the ESP32, upload the following I2C Scanner sketch.

Displaying static text on the LCD is very simple. All you have to do is select where you want the characters to be displayed on the screen, and then send the message to the display.

The next two lines set the number of columns and rows of your LCD display. If you’re using a display with another size, you should modify those variables.

Scrolling text on the LCD is specially useful when you want to display messages longer than 16 characters. The library comes with built-in functions that allows you to scroll text. However, many people experience problems with those functions because:

In a 16×2 LCD there are 32 blocks where you can display characters. Each block is made out of 5×8 tiny pixels. You can display custom characters by defining the state of each tiny pixel. For that, you can create a byte variable to hold  the state of each pixel.

In summary, in this tutorial we’ve shown you how to use an I2C LCD display with the ESP32/ESP8266 with Arduino IDE: how to display static text, scrolling text and custom characters. This tutorial also works with the Arduino board, you just need to change the pin assignment to use the Arduino I2C pins.

We hope you’ve found this tutorial useful. If you like ESP32 and you want to learn more, we recommend enrolling in Learn ESP32 with Arduino IDE course.

The purpose of this guide is to get your 0.96″ color LCD display successfully operating with your Arduino, so you can move forward and experiment and explore further types of operation with the display. This includes installing the Arduino library, making a succesful board connection and running a demonstration sketch.

With the support of LiquidCrystal library, we even can use LCD WITHOUT knowing the meaning of these pins. However, if you are curious or want to know in-depth, let"s see these pins and their functionality:

Vo (LCD Contrast) pin: controls the contrast and brightness of the LCD, can be connected to 5V (the highest contrast and brightness), or connected to a potentiometer (to adjust to the contrast and brightness)

RS (Register Select) pin: There are two kinds of data that need to send to LCD: command (to control LCD) and data. These two are sent on the same data bus. RS pin tells the LCD whether the data on the data bus is the commands or the data.

8-bit mode is faster than the 4-bit mode, but use more pins than 4-bit mode. The mode selection is performed at the initialization process by sending a command to LCD.

Controlling LCD is a quite complicated task. Fortunately, thanks to the LiquidCrystal library, this library simplifies the process of controlling LCD for you so you don"t need to know the low-level instructions. You just need to connect Arduino to LCD and use the functions of the library. The using LCD is a piece of cake.

In this project, we will learn how to interface Nokia 5110 LCD with ESP32 DevKit Development Board. We will see a little bit about the Nokia 5110 LCD, the PCD8544 Driver IC from Phillips, how the ESP32 Nokia 5110 Interface works and also display some text and graphics on the Nokia 5110 LCD using ESP32.

The Nokia 5110 LCD Module is a brilliant choice for this purpose. Originally used in the Nokia 3110 and Nokia 5110 Mobile Phones, the Nokia 5110 LCD has become a popular display device within the DIY community due to low cost, compact size and simple interface.

This and the support from the Arduino Community (and other open-source communities) for drivers, makes the Nokia 5110 LCD a must use display device in our projects.

Nokia 5110 LCD Module is based on the PCD8544 LCD Controller IC from Phillips. It is capable of driving 84 columns and 48 rows, which unironically, is the resolution of the Nokia 5110 LCD i.e., 84×48 pixels.

An important thing to remember is the Nokia 5110 LCD and the PCD8544 Controller works on 3.3V supply. This won’t be an issue as we are working with ESP32, which is also 3.3V device. But if you plan to use Nokia 5110 LCD with Arduino (or other 5V microcontrollers), then you need to make proper logic level conversions.

Also, the Nokia 5110 LCD Module comes with a bunch of backlight color options like: red, blue, white, yellow and green. In my case, I got the blue backlight model.

Enough theory. Let us proceed with interfacing Nokia 5110 with ESP32. But first, let us take a quick look at the pinout of the Nokia 5110 Module. The following table and image show the pinout of Nokia 5110 LCD.

As you can see from the image, the Nokia 5110 LCD (or rather the PCD8544 Controller) uses an SPI like serial interface to communicate with a microcontroller. So, we have to use the SPI pins of the ESP32 Microcontroller.

I will use the VSPI interface in this project. We need the MOSI, CLK (SCK) and CS pins from the hardware VSPI interface. The Reset (RST) and Data / Command (DC) pins of the Nokia 5110 LCD can be connected to any GPIO pins of ESP32.

You can another GPIO Pin to control the backlight of the LCD but I opted for always on backlight and hence I connected the ‘BL’ pin of Nokia 5110 LCD to 3.3V supply through a 220Ω current limiting resistor.

You need to download two libraries for Nokia 5110 LCD in the Arduino IDE. They are the device specific ‘Adafruit PCD8544 Nokia 5110 LCD Library’ and a supporting ‘Adafruit GFX’ library. If you worked with Nokia 5110 LCD and installed these libraries before, then you can skip this step.

Make all the connections as mentioned earlier and connect the ESP32 to the computer. Go to Tools -> Board and make sure that ‘ESP32 Dev Module’ is selected. Also use the correct COM port.

This is a simple code to demonstrate how easy it is to display text on Nokia 5110 LCD using ESP32. You can try other options like display different shapes, normal text and inverted text, change the font and size etc.

One of the useful features of Nokia 5110 LCD is you can digitally adjust the contrast of the display using a function ‘setContrast’. This is very helpful if you want a software control of the contrast rather than a physical adjustment (like in 16×2 Character LCD).

So, I made a small circuit where I connected a 5 KΩ POT to ADC1 channel 6 of ESP32. And based on the output of the ADC, I am setting the contrast of the Nokia 5110 LCD Display.

One important thing to remember is that ADC in ESP32 has 12-bit resolution. Which means the output digital values of the ADC conversion will be in the range of 0 – 4095. But the range of contrast values which the Nokia 5110 LCD can accept is between 0 and 100.

A simple project involving ESP32 Development Board and Nokia 5110 LCD. You learned about Nokia 5110 LCD, the PCD8544 LCD Controller, how the ESP32 Nokia 5110 LCD interface works and how to display simple text on Nokia 5110 using ESP32.

This article includes everything you need to know about using acharacter I2C LCD with Arduino. I have included a wiring diagram and many example codes to help you get started.

Once you know how to display text and numbers on the LCD, I suggest you take a look at the articles below. In these tutorials, you will learn how to measure and display sensor data on the LCD.

Each rectangle is made up of a grid of 5×8 pixels. Later in this tutorial, I will show you how you can control the individual pixels to display custom characters on the LCD.

They all use the same HD44780 Hitachi LCD controller, so you can easily swap them. You will only need to change the size specifications in your Arduino code.

The 16×2 and 20×4 datasheets include the dimensions of the LCD and you can find more information about the Hitachi LCD driver in the HD44780 datasheet.

After you have wired up the LCD, you will need to adjust the contrast of the display. On the I2C module, you will find a potentiometer that you can turn with a small screwdriver.

Note that counting starts at 0 and the first argument specifies the column. So lcd.setCursor(2,1) sets the cursor on the third column and the second row.

Next the string ‘Hello World!’ is printed with lcd.print("Hello World!"). Note that you need to place quotation marks (” “) around the text since we are printing a text string.

The example sketch above shows you the basics of displaying text on the LCD. Now we will take a look at the other functions of the LiquidCrystal_I2C library.

This function turns on automatic scrolling of the LCD. This causes each character output to the display to push previous characters over by one space.

I would love to know what projects you plan on building (or have already built) with these LCDs. If you have any questions, suggestions or if you think that things are missing in this tutorial, please leave a comment down below.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

Previous examples connect the white LED backlight to power. The following example is specifically for those using an LCD with a RGB LED backlight. The only difference between the connection is the LED"s backlight on pins 15-18.

LCD Displays are a fast and inexpensive way to display simple information. This tutorial will demonstrate how to connect a 16x2 LCD display using I2C to an ESP8266 NodeMCU dev kit.

The LCD display I"m going to use is fairly common and can be picked up for a couple of bucks from Amazon. It uses I2C to communicate with the NodeMCU. I2C is nice because it only required two wires for communication.

Connect the VCC pin on the LCD display to the VIN pin on the NodeMCU. The VIN pin on the NodeMCU is tied directly to the 5V pin on the incoming USB port. If you plan on powering the NodeMCU with something other than USB, you"ll have to find another way to provide 5V to the display.

The LCD display works by first moving the cursor to where you want to start and then printing some characters. In my example, I wanted HELLO and WORLD to be centered on each line. For "HELLO", the cursor needed to be 5 characters from the right and zero characters down, so I moved it (5, 0). For "WORLD", I needed it to be 5 characters to the right and one character down, so I moved it (5, 1).

In this digital age, we come across LCDs all around us from simple calculators to smartphones, computers and television sets, etc. The LCDs use liquid crystals to produce images or texts and are divided into different categories based on different criteria like type of manufacturing, monochrome or colour, and weather Graphical or character LCD. In this tutorial, we will be talking about the 16X2 character LCD Modules.

The 16x2 LCDs are very popular among the DIY community. Not only that, but you can also find them in many laboratory and industrial equipment. It can display up to 32 characters at a time. Each character segment is made up of 40 pixels that are arranged in a 5x8 matrix. We can create alphanumeric characters and custom characters by activating the corresponding pixels. Here is a vector representation of a 16x2 LCD, in which you can see those individual pixels.

As the name indicates, these character segments are arranged in 2 lines with 16 characters on each line. Even though there are LCDs with different controllers are available, The most widely used ones are based on the famous HD44780 parallel interface LCD controller from Hitachi.

The 16x2 has a 16-pin connector. The module can be used either in 4-bit mode or in 8-bit mode. In 4-bit mode, 4 of the data pins are not used and in 8-bit mode, all the pins are used. And the connections are as follows:

Vo / VEE Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backwards to adjust the LCD contrast.

The 16x2 LCD modules are popular among the DIY community since they are cheap, easy to use and most importantly enable us to provide information very efficiently. With just 6 pins, we can display a lot of data on the display.

The module has 16 pins. Out of these 16 pins, two pins are for power, two pins are for backlight, and the remaining twelve pins are for controlling the LCD.

If you look at the backside of the module you can simply see that there are not many components. The main components are the two controller chips that are under the encapsulation. There is an onboard current limiting resistor for the backlight. This may vary from different modules from different manufacturers. The only remaining components are a few complimentary resistors for the LCD controller.

In the module PCB, you may have noticed some unpopulated footprints. These footprints are meant for charge pump circuits based on switched capacitor voltage converters like ICL7660 or MAX660. You can modify your LCD to work with 3.3V by populating this IC and two 10uF capacitors to C1 and C2 footprint, removing Jumper J1 and adding jumper J3. This modification will generate a negative contrast voltage of around 2.5V. This will enable us to use the LCD even with a VCC voltage of 3.3V.

To test whether a 16x2 LCD works or not, connect the VDD, GND and backlight pins to 5v and GND. Connect the centre terminal of a 10K variable resistor to the VEE pin. Connect the other two terminals to VCC and GND. Simply rotate the variable resistor you will see that the contrast will be adjusted and small blocks are visible. If these rectangles are visible, and you were able to adjust the contrast, then the LCD is working

There are 16 pins on the display module. Two of them are for power (VCC, GND), one for adjusting the contrast (VEE), three are control lines (RS, EN, R/W), eight pins are data lines(D0-D7) and the last two pins are for the backlight (A, K).

The 16x2 LCD has 32 character areas, which are made up of a 5x8 matrix of pixels. By turning on or off these pixels we can create different characters. We can display up to 32 characters in two rows.

Controlling the LCD module is pretty simple. Let’s walk through those steps. To adjust the contrast of the LCD, the Vo/ VEE pin is connected to a variable resistor. By adjusting the variable resistor, we can change the LCD contrast.

The RS or registry select pin helps the LCD controller to know whether the incoming signal is a control signal or a data signal. When this pin is high, the controller will treat the signal as a command instruction and if it’s low, it will be treated as data. The R/W or Read/Write pin is used either to write data to the LCD or to read data from the LCD. When it’s low, the LCD module will be in write mode and when it’s high, the module will be in reading mode.

The Enable pin is used to control the LCD data execution. By default, this pin is pulled low. To execute a command or data which is provided to the LCD data line, we will just pull the Enable pin to high for a few milliseconds.

To test the LCD module, connect the VDD, GND, and backlight pins to 5v and GND. Connect the center terminal of a 10K variable resistor to the VEE pin. Connect the other two terminals to VCC and GND as per the below connection diagram-

Simply rotate the variable resistor you will see that the contrast will be adjusted and small blocks are visible. If these rectangles are visible, and you were able to adjust the contrast, then the LCD is working.

Let’s see how to connect the LCD module to Arduino. For that first, connect the VSS to the GND and VDD to the 5V. To use the LCD backlight, connect the backlight Anode to the 5V and connect the backlight cathode to the GND through a 220Ωresistor. Since we are not using the read function connect the LCD R/W pin to the GND too. To adjust the contrast, connect the centre pin of a 10KΩ trimmer resistor to the VEE pin and connect the side pins to the VCC and GND. Now connect the registry select pin to D12 and Enable pin to D11.

Now let’s connect the data pins. The LCD module can work in two modes, 8-bit and 4-bit. 8-bit mode is faster but it will need 8 pins for data transfer. In 4-bit mode, we only need four pins for data. But it is slower since the data is sent one nibble at a time. 4-bit mode is often used to save I/O pins, while the 8-bit mode is used when speed is necessary. For this tutorial, we will be using the 4-bit mode. For that connect the D4, D5, D6 and D7 pins from the LCD to the D5, D4, D3 and D2 pins of the Arduino.

The following Arduino 16x2 LCD code will print Hello, World! on the first line of the display and the time the Arduino was running in seconds on the second line.

Now let’s discuss the code. As usual, the sketch starts by including the necessary libraries. For this tutorial, we will be including the LiquidCrystal library from Arduino. This library is compatible with LCDs based on the Hitachi HD44780, or any compatible chipset. You can find more details about this library on the Arduino website.

Let’s create an object to use with the LiquidCrystal library. The following line of code will create an object called lcd. We will be using this object in the entire code to access the library functions. The object is initialized with the pin numbers.

Now let’s look at the setup()function. The lcd.begin function is used to initialize the LCD module. This function will send all the initialization commands. The parameters used while calling this function are the number of columns and the number of rows. And the next function is lcd.print. with this function, we have printed the word Circuit Digest! to the LCD. Since the LCD cursor is set to home position within the lcd.begin, we don’t need to set any cursor position. This text will stay there for two seconds. After that, the text will scroll from left to right until the entire text is out of the display. To scroll the display to the right, we have used the function lcd.scrollDisplayRight. After that, to clear display, we used lcd.clear, this will clear any characters on the display.

Now let’s look at theloop function. The for loop will count from 0 to 9, and when it reaches 9, it will reset the count and repeat the process all over again. lcd.setCursor is used to set the cursor position. lcd.setCursor(8, 1) will set the LCD cursor to the eighth position in the second row. In the LCD, the first row is addressed as 0 and the second row is addressed as 1. And the lcd.print(i) will print the count value stored in the variable i to the display.

Wrong characters are displayed: This problem occurs usually when the LCD is not getting the correct data. Make sure you are sending the correct ASCII value. If you are sending the correct ASCII characters, but still showing the wrong one on the LCD, check your connections for loose contact or short circuits.

Contrast and delay are ok, but still no display: Make sure you are powering the LCD from a 5V source. By default, these displays won’t work with a supply voltage below 5V. So if you are using the display with a 3.3V microcontroller make sure to power the display from 5V and use level shifters in between the display and the microcontroller.

In this project we will provide the input voice using Google Voice Keyboard via a Android App (BlueTerm) and print the text on 16x2 LCD using Raspberry Pi.

In this tutorial we are interfacing a Liquid Crystal Display (LCD) module with the Raspberry Pi Pico using Micropython to display strings, and characters on the LCD.

We used some Python scripts to find the local IP address of your Raspberry Pi on the network and display it on the 16x2 LCD Screen. We also added the script in the Crontab so that it can be run on every 10 minutes and we will have the updated IP address every time.
