LCD 16x2 Display

The LCD 16x2 Display project demonstrates how to interface a 16x2 character LCD (Liquid Crystal Display) with an Arduino Mega. The project initializes the LCD, displays a greeting message on the first line, and then continuously updates the second line with the number of seconds since the Arduino board was last reset.

Components Needed

• Arduino Mega
• 16x2 LCD Display
• Potentiometer (for contrast adjustment)
• Jumper Wires
• Breadboard
• Power Supply

Instructions

Circuit Setup:

Connect the 16x2 LCD display to the Arduino Mega as described in the circuit setup section.

Libraries:

Ensure you have installed the

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 LCD display. The first line should display "Hello, Arduino!" and the second line should display the number of seconds since the Arduino board was last reset, updating every second.

Notes

Adjust the

Ensure the potentiometer is adjusted correctly for optimal contrast on the LCD display.

Secure all connections properly to avoid loose connections which could affect the display.
