In this tutorial let's interface a 16x1,16x2 and 20x4 character display with AVR breakout board. For this tutorial we will require a LCD Breakout.

Basics

LCD can be interfaced with AVR breakout in two modes i.e. 8 bit and 4 bit. Let's interface it in 4 bit mode.We will connect the display in 4 bit mode. You can change it to 8 bit mode making changes in connections and corresponding code. Hardware connections remain same for LCD 16x1,16x2,20x4 as shown in hook up.
