Driving an LCD With I2C Module

In this tutorial we will see how an LCD screen works and how to use it more easily with the I2C module

An LCD (liquid crystal display) is a device that can display characters while consuming a lot of electricity is why it is found in several electronic project

The I2C (Inter-Integrated Circuit) is a computer bus Designed by Philips for home automation and home electronics applications, it makes it easy to connect a microprocessor and different circuits by reducing the number of lines required to only two lines, SDA (Serial DAta), and SCL (Serial CLock).

You have to know that we are going to Display the characters in the LCD as if it were a table each box of the table represents a space to display a character in the screen (See diagram below)

For the assembly nothing more simple:

you can solder the I2C module and the LCD screen like this

note that the A5 PIN also represents the SCL pin and the A4 pin represents the SDA pin
