I2C 16x2 LCD Display is a display module consisting of 2 rows and 16 columns, used to display text and numeric data in microcontroller projects. Unlike standard LCDs, it works with only 4 wires (VCC, GND, SDA, SCL) thanks to the I2C converter on it. In this way, it prevents complex cable crowding and saves pins in your projects. Contrast can be adjusted with the potentiometer on the back and the backlight can be controlled in software.
