Today we are going to look at how to drive the low cost, big, Arduino 3.5 Color TFT display.At the end of this tutorial, we would have learned how to use this interesting display with the Arduino Uno and Mega boards.It is based on the ILI9481 TFT driver, comes with an SD card slot at the back and it is pre-soldered with pins for easy mount on the Arduino Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.
The price of the display is very low for such a big display, it costs 10 and banggood.com were kind enough to send me a sample unit in order to test it and share my opinion about it with you. I will be performing demos such as showing how Images stored on an SD card and inserted into the SD slot of the display can be shown on the display. Since the module comes in a shield form, all we need to do is to snap it onto the top of the Arduino Uno as shown in the image below. If we dont use the SD card slot, we will be left with 6 digitals pins and one analog pin which can be connected to other modules or sensors. Unfortunately, this display does not work with some other Arduino Uno form factor based boards like the Arduino Due or the Wemos D1 ESP8266 board due to pin compatibility and library Issues. The Wemos D1, in particular, has just one analog pin and the display requires 5. Since the display uses the familiar Adafruit libraries, we can easily build several impressive projects. ![]() Arduino Uno Library Code Of ThisYou can download the code of this simple example for the Arduino 3.5 Color TFT display by clicking on the download link below or by clicking on the link in the description of the video. To begin we clear the LCD of previous settings, then set the type LCD we are using via the LCD.begin function. With this done, we set the rotation of the TFT and proceed to fill the screen with different colors. The void loop section basically echoes some of the things we tried under the void setup function. The idea behind all of this is to show you what is possible with this wonderful display. If you get stuck at any point while building this project, feel free to reach out to me via the comment section, I will be glad to answer whatever questions you might have. I just need to know if we could make scrolling type mechanism into my tft if yes need some help as well waiting for your reply. I love teaching what I know and sharing my experiences with you.
