I2C Module for Character LCD

2×16 Character LCD is most popular display component for small controller like Arduino, but most of these LCD uses parallel interface. In most of the case, you will need 10 pins to control it or to display message on it. 8-pin are for the data, Enable and Latch pin for signal control. Minimum, you will need 6-pin for 4-bit mode interface. Still a lot of pins being used up 🙁

This I2C module for LCD will help you save all those precious pins. This module will only need 2 GPIO pins (specifically I²C pins) to send message to Character LCD.
