The latest Chinese TFT displays are quite low in price but work perfectly with Arduino and Raspberry Pi. There are two different types of TFT shields available: one with 26 pins (13×2 DIL) for Raspberry Pi and the other as Arduino TFT shield for Arduino Uno board.

Arduino TFT shield can be perfectly mounted on top of an Arduino Uno board. But a major disadvantage is that after mounting the shield on Arduino Uno board, it is difficult to use its GPIO pins for any other application.

The Arduino TFT shield has a micro SD card attached that gets connected to its serial peripheral interface (SPI) pins for communication with the microcontroller. This micro SD card is not used in this project.

This project creates an analogue dial clock along with digital date, time and temperature display using an LM35/TMP36 temperature sensor. The time signal is derived from a U-Blox NEO-6M GPS receiver module. Once the technique is understood, it can be deployed for many other applications.

The connections are easy to make as shown in Fig. 2. The pin connections of the Arduino TFT shield are straightforward; you just need to mount the shield on top of the Arduino Uno board. The pin-to-pin connection details between TFT shield and Arduino Uno are given in the table.

Since top portion of the Arduino Uno is covered by TFT shield, the connections for the TMP36 and GPS receiver are taken from the bottom side of the Arduino Uno board (refer Fig. 3). In case you want to free some Arduino pins then you should see the mcufriend_shield.h file and re-write the connections to do so.

Writing the Arduino code/sketch (GPS_analog_clock.ino) for the project is real fun! You can make TFT display in many different ways through coding. Creating a thick border line, making the hour and minutes hands move smoothly were quite challenging as Adafruit_GFX library is not so much developed. High school trigonometry is all that you need to make it happen for you.

After uploading the code, solder the pins of TMP36 and GPS module to the Arduino board. Then mount the TFT shield on top of the Arduino board. After all the connections are done as per Fig. 2, connect it to 3.3V DC source. GPS module requires a few minutes to trace the satellites.

Most GPS receivers have an inbuilt patch antenna that can locate the low Earth orbit (LEO) GPS satellites very easily, even if your room’s windows are closed. As soon as two such satellites are located, the time starts appearing on the analogue dial. At the same time, the date, time and temperature are shown digitally on right side of the TFT display.

I bought a cheap LCD screen for a project I"m working on to get my feet wet with programming LCD touch screens before buying a "full-size" screen. But i can not find any libraries or code to get it to display anything. Ive downloaded the new ILI9341 library along with 4-5 other ones and can not get it to display or do anything.

Nothing can be compared when you can put your hard work to display on a 4” TFT display- From one end to the other end it"s 480*360 pixel to play with. 4” TFT Analog-GPS clock on Arduino

Every electronic hobbyist dreams to display his work on display – be it LCD, GLCD (64*128), OLED or TFT . LCDs are the oldest type of displays. If putting your work on LCD or GLCD is great then putting it on OLED is certainly greater but nothing can be compared when you can put your hard work to display on a 4” TFT display. From one end to the other end it"s 480*360 pixel to put up with and it"s very very impressive.

The latest Chinese TFT displays are very cheap and works perfectly with Arduino & Raspberry Pi. The TFT ILI9488 display costs about $8 on aliexpress.com. There are two varieties available one with 26 pins 13*2 DIL and the other is with pins aligned exactly to sit on an UNO board.

Arduino style – Directly sits exactly on an Arduino UNO board. The major disadvantage is that once it sits on an UNO board one can hardly use any other GPIO pins for other usages. Both these styles I"ve used for creating art works on Arduino & Raspberry Pi. The Arduino type has an extra SDCard attached and gets connected to the SPI (D-10,11,12,13) pins when inserted.

While the pin connections of the Arduino type is pretty clear and straight forward the same on Raspberry Pi type is not clear at all. However, here"s my hard work for you to make your life easy ! [See the connection diagram for both the types]

While the Arduino type shield is fairly easy to connect but difficult to attach other devices , the Raspberry Pi type shield is little difficult to find out the pin details but it has extremely easy & compact interface while fitted up . Here"s the 26 pin DIL pin details which will go to the same pins of Arduino.

These shields are basically for 3.3 volt operations. But upto 5 volt it works , However, prolong operation on 5 volt is not recommended as it gets heated up profusely. In case you want to free some other Arduino pins then you look into the mcufriend_shield.h file and re-write the connections as I shifted some connections to alternate pins.

Construction:The possibilities are limitless when you can tie up the display so easily. Here"s a GPS ana-digital clock with temperature indicator built with the following Bill Of Materials.

The connections are easy as shown in the schematic diagrams. Since all the top portion of the UNO is covered by the TFT shield, the connections for the LM-35, GPS receiver is taken from the bottom side of the UNO shield.

Software: This is real fun ! With small strokes of code the TFT behaves differently and opens up many different ways of displaying the output. Creating a thick line, making the hands move smoothly was real challenge as the Adafruit_GFX is not so much developed but a look back to the high school trigonometry is all that you need to make it all happen for you.

Operation:The present GPS receivers which have a built in patch antenna on top ,can locate the LEO GPS satellite very easily if you have your windows are open or glass covered. The moment it locates 2 such satellites ,the time starts ticking on the analog dial. At the same time the time is shown digitally on the right side with the temperature display at the bottom. For temperature sensor I"ve used a TMP36 sensor which works on 3.3 volt. However, an LM35 can also be used but you have to have 5volt supply for that.

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image to code and then used two black and white arcs to create the pointer of volumes.  Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image and use the arc and print function to create this gauge.  Download the .h file and add it to folder of the Arduino sketch.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

Garlow is a mini GPS Watch that is based on the Arduino Nano board. It’s not really that “mini” compared to other commercial GPS watch like the Garmin, but I really made a great effort to bring the size down. In fact it looks more like a GPS clock. The first version Arduino GPS logger I built was based on the Arduino UNO, and it was larger than 2 packs of poker cards stacked together. It works just as well as a Garmin GPS watch.

Garlow stands for GPS Arduino RechargeableLogger OLED Watch. It does what the name suggests: Accurate time, positioning related information are received from GPS satellites, and they can be logged on SD card and shown on a OLED display. It can be carried as a watch or simply left at the back seat of your car as a GPS data logger. The whole system is built on the backbone of an Arduino Nano board, with a Lipo power module which enables USB battery recharge.

During the development of this Arduino GPS watch, I discovered so many things and techniques that I didn’t know about the Arduino, for example I didn’t know you could save data on EEPROM, which is unaffected by power down.

If you don’t know how GPS receiver works, check out my previous Arudino GPS tutorials first. It’s much easier to use a GPS library to help decoding the gps nmea sentences, and get the useful data directly. I am using TinyGPS for this project.

The SD card module is a random one I found on eBay where the Chinese manufacturers have made it dirt cheap (only $5). Most of them works with Arduino using SPI communication. There is a standard SD library provided by the Arduino Official, and here is a tutorial on this. However it was causing flash memory problem for me.

This is a tricky one. I written my sketch, and tested the GPS and OLED display, everything was working great, until I added the SD Card module, and the Arduino IDE was telling me my sketch is too big to upload!

I am using a 600mAh 1S Lipo battery from my little quadcopter. With the Arduino Nano’s analog input, I am able to check the battery voltage by connecting the battery+ to the analog pin directly. Same reason in the Bike Light project, I had to put a push button in between, so when it’s not pressed, it’s a open circuit. Otherwise current will be drawn from the battery constantly.

When it came to programming, It was quite a challenge for me. It wasn’t because of the complexity of the coding, but I was stuck with the limited sketch space on the Arduino. I kept getting “Sketch is too big” error, and I was struggling to try to reduce the size of my program. Following my previous post about tips on reducing Arduino sketch size, I was able to cut the compiled size of my code down, just under the limit of the Arduino UNO (around 32K KB), but still it’s 2KB over the limit of Arduino Nano.

This GPS clock draws a total current of 40mA at standby mode (OLED turned off, SD card Modue turned off, only GPS working), and at 80mA normal operation (all on). The current consumption can be broken down to:

The GPS positioning accuracy is about +/- 3 meters, as you can see from the video the result is zigzag. Update rate is very good which is 10Hz. It also works indoor but needs to be close to the windows.

The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

As mentioned above, the ST7789 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V (between VCC and GND) which comes from the Arduino board.

To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.

The first library is a driver for the ST7789 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7789” and install the one from Adafruit).

The Arduino board has a wide variety of compatible displays that you can use in your electronic projects. In most projects, it’s very useful to give the user some sort of feedback from the Arduino.

With the TFT display you can display colorful images or graphics. This module has a resolution of 480 x 320. This module includes the SD card socket and SPI FLASH circuit.

A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?Although the Nextion MIDI I/O interface  has been primarily designed as an add-on for Nextion HMI screens to transform these in fully autonomous MIDI devices as shown in previous blog posts here, it is also of great use for any Arduino based electronic music project! Many MIDI projects for Arduino suffer from a lack good hardware support. There are sophisticated code, excellent libraries and an infinity of use cases, but afterwards, things tend not to work in a rather rough environment in the studio or on stage. That"s because two resistors and a few Dupont wires on a breadboard besides the Arduino are not really an interface which could drive your Synth, Sequencer, or Drum machine over a 5m long MIDI cable.
