How To Connect A Serial LCD To An Arduino UNO

Connect a serial LCD to an Arduino UNO. via instructables

In this instructable I will show you how I connected a serial LCD 16X2 to an Arduino UNO.

There are lots of instructables and tutorials showing you how to connect a regular LCD to an Arduino but not many showing a serial LCD and on my Arduino the PINS to attach the UART pins are hidden. With this instructable I will shed some light on this issue 🙂

One of the reasons why you would be using a serial LCD is the fact that it uses only 4 PINS instead of 16.

The UART or serial module that is attached to the back of the LCD is responsible for sending and receiving serial communications between the Arduino and the LCD and it has a onboard potentiometer to adjust the brightness of the screen.
