#1602 lcd

Today, we are going to talk about a Display Device which we use to display input and outputs. It is a 16X2 LCD display.

Here, we will use and arduino mega board and interface an lcd with it.

The components required for the interfacing are as follows:

1. Arduino Mega.

2. 16X2 LCD Module.

3. 10 K Potentiometer.

4. Bread Board.

5. Connecting Wire.

6. USB Cable.

The steps to interface LCD are as follows:

1. Fix the LCD Module onto the Breadboard firmly.

2. Connect PIN1 of LCD with GND.

3. Connect PIN2 of LCD with VCC.

4. Connect PIN3 of LCD with Potentiometer. This is the contrast pin.

5. Connect PIN4 of LCD with PIN7 of Arduino.

6. Connect PIN5 of LCD with GND. This is the RW pin of LCD. This must be low for writing onto the LCD.

7. Connect PIN6 of LCD with PIN6 of Arduino. This is the Enable pin of LCD.

8. Now connect the D4-D7 Pins of LCD with PIN 5,4,3,2 of the Arduino. These are the Data pins of the LCD and it will Work on the 4 Bit mode.

9. Now, Connect PIN15 of LCD with VCC and PIN16 with GND. These are the pins of Backlight Led.

10. Now, Write the code as shown in the video and upload the Code.

Your interfacing of LCD With Arduino is complete.
