Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

The display is based on the popular ILI9481 chipset and works with 5V so it can be used with all Arduino compatible boards. Just plugin and start coding.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6236 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.

The pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (Due/Mega 2560).

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

This TFT 3.5 Inch LCD display support 480x320 pixel resolutions. The display uses the ILI9481 graphics controller. The module includes the 5V-3.3V power conversion circuit and no additional level conversion circuitry is required. This Module can be inserted directly into the Arduino Mega2560 Board.

The display is based on the popular ILI9481 chipset and works with 5V so it can be used with all Arduino compatible boards. Just plugin and start coding.

Hey guys, its Nick again, welcome once again to educ8s.tv a channel that is all about DIY electronics projects with Arduino, Raspberry Pi, ESP8266 and other popular boards. 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.

The display is quite big and offers a resolution of 480×320 pixels. 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.

Few weeks ago, I discovered this Arduino 3.5″ Color TFT display on Banggood.com and thought it will be useful in some of our projects because of its size and its low price. 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.

As shown in the video, we will be performing simple tasks with the display to demonstrate how it works and how you can integrate it in your project. 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.

Connecting the module to the Arduino is very easy. 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.

One of the few downsides to this display is the amount of the Arduino pins it uses. If we don’t 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. but when we use the SD card module part of the display, we will be left with just 2 digital and one analog pin which at times limits what we the kind of project for which we can use this display but fortunately, this display is also compatible with the Arduino Mega board which offers many more digital pins to work with, so when you need extra pins, and size is not an issue, use the mega. 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.

To use this display, we will need the libraries which can found on the product page on banggood.com. All we have to do is to install the library and load any of the examples that are designed for this shield. Since the display uses the familiar Adafruit libraries, we can easily build several impressive projects. I have developed a simple program just to demonstrate how easy it is to use the display thanks to the Adafruit libraries! It uses some of the basic functions in order to display text and simple graphics. You 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.

With this done, we then write the void setup() function. 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.

That’s it for today’s tutorial guys, thanks for reading/watching. 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. Don’t forget to share, like and subscribe on youtube. Thanks!
