LCD character displays

There is nothing better than writing any information from the Arduino to a small LCD character display. They are incredibly handy and just look plain cool. Even better, Arduino has a built-in library to do this. Let's explore how we can implement it.

Getting ready

We will need the following ingredients for this recipe:
