3.5″ 320×480 ILI9486 TFT LCD Arduino Shield for Arduino UNO MEGA2560 Board COM42 ,R16

Description

The 3.5″ 320×480 ILI9486 TFT LCD Arduino Shield is a 3.5-inch TFT LCD module with 320×480 resolution and 65K color display. It uses 8-bit line parallel port communication, and the driver IC is ILI9486. The module includes an LCD display, 5V~3.3V level conversion circuit, which can be directly plugged into the Arduino UNO and MEGA2560 development boards, and also supports SD card expansion function.

Hardware required

• 3.5″ 320×480 TFT LCD Arduino Shield
• Arduino UNO

Step 1: Install the Necessary Libraries

1. Open the Arduino IDE.
2. Navigate to Sketch > Include Library > Manage Libraries to open the Library Manager.
3. Search for DIYables TFT Shield and click Install. This should also automatically install the required Adafruit GFX library.
4. Alternatively, you can download the library as a ZIP file from the GitHub repository and install it using Sketch > Include Library > Add .ZIP Library.

Step 2: Connect the 3.5″ 320×480 ILI9486 TFT LCD Arduino Shield

• Carefully align the pins of the 3.5″ TFT LCD shield with the headers on your Arduino Uno board.
• Gently push the shield down until it is securely seated on the Uno board. No external wiring is needed for a non-touch shield.

Step 3: Load a Test Example Sketch

1. In the Arduino IDE, go to File > Examples.
2. Scroll down to find the DIYables TFT Shield examples.
3. Select an example sketch, such as ShowTextAndNumber or DrawImage, to test basic graphics and text functions.

Step 4: Configure and Upload the Code

1. Select your board: Go to Tools > Board > Arduino AVR Boards and select “Arduino Uno”.
2. Select the correct COM port: Go to Tools > Port and choose the port your Arduino Uno is connected to.
3. Compile the program: Click the Verify (checkmark) button to compile the code and check for errors.
4. Upload the program: Click the Upload (right arrow) button to upload the sketch to your Arduino Uno.
