In this video I’m demonstrating how to start using a 16×2 LCD with an Arduino. The first example displays a static text message and number of seconds since Arduino reset. The next one covers modification of my Arduino ohmmeter project to display data on the 16×2 Hitachi HD44780 LCD.
It is a step by step tutorial, which will walk you through wiring the alphanumeric (text) LCD to work with Arduino Uno. You will also learn how to write a sketch (program), which lets you control the liquid-crystal display with the Arduino.
