Connect Arduino With LCD

Display units are very important to communicate between the real world and the machine world, but without the help of digital electronics, it's almost impossible. speaking about digital electronics I will use an Arduino to control the display so let's get started.

Step 1: Components Requirement

An Arduino

10k potentiometer


A couple of jumper wires

16X2 LCD

Male Header Pins

Step 2: LCD Pin Config

Step 3: Circuit Diagram

LCD GND to Arduino GND

LCD VCC to Arduino 5V rail

LCD contrast pin goes to the 10K pot

LCD RS pin to digital pin 12

LCD Enable pin to digital pin 11

LCD D4 pin to digital pin 5

LCD D5 pin to digital pin 4

LCD D6 pin to digital pin 3

LCD D7 pin to digital pin 2
