LCD TFT Display

The LCD TFT Display project demonstrates how to interface a TFT LCD (Thin Film Transistor Liquid Crystal Display) with an Arduino Mega using the Adafruit GFX and Adafruit TFTLCD libraries. This project initializes the TFT LCD, fills the screen with a color, and prints a message on the display.

Components Needed

• Arduino Mega
• TFT LCD Display (ILI9341 compatible)
• Adafruit GFX Library
• Adafruit TFTLCD Library
• Jumper Wires
• Breadboard
• Power Supply

Circuit Setup

Connect the TFT LCD Display to Arduino Mega:

Instructions

Circuit Setup:

Connect the TFT LCD display to the Arduino Mega as described in the circuit setup section.

Libraries:

Install the Adafruit GFX library and Adafruit TFTLCD library in your Arduino IDE (Library Manager:

Code Upload:

Open Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

Observe the TFT LCD display. It should fill the screen with a blue color and display the message "Hello, Arduino!" at coordinates (50, 50).

Applications

Notes
