There are many colour LCDs on the market that can be used with an Arduino, and for this tutorial we’re using a relatively simple model available that is available from suppliers such as Linksprite (and previously Sparkfun), based on a small LCD originally used in Nokia 6100 mobile phones:

These are a convenient and inexpensive way of displaying data, or for monitoring variables when debugging a sketch. Before getting started, a small amount of work is required.

From the two examples we have seen, neither of them arrive fitted with stacking headers (or in Sparkfun’s case – not included) or pins, so before doing anything you’ll need to fit your choice of connector. Although the Linksprite shield arrived with stacking headers, we used in-line pins as another shield would never be placed on top:
