I2C LCD 16X2 Interfacing with Arduino
Hello and Welcome to Alpha Electronz.!We provide Tutorials (Post + Videos) about Projects based on Arduino, Raspberry Pi, etc.
In this Tutorial we are going to Interface I2C LCD 16X2 Module with Arduino Uno and display our Name on LCD.
Before starting we should first Understand what I2C is?
I2C Communication Protocol
I2C combines the best features of SPI and UARTs. With I2C, you can connect multiple slaves to a single master (like SPI) and you can have multiple masters controlling single, or multiple slaves. This is really useful when you want to have more than one microcontroller logging data to a single memory card or displaying text to a single LCD.
Like UART communication, I2C only uses two wires to transmit data between devices:
SDA (Serial Data) — The line for the master and slave to send and receive data.
SCL (Serial Clock) — The line that carries the clock signal.
I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line).

The Connections are as Follows:
GND –> GND
VCC → 5V
SDA → A4
SCL → A5
Hope you like the Tutorial.
