If you know how to program with the Arduino there are a number of projects you can tackle to gain more experience.
For example, you can build a project based on the following stages:
1) Build a digital stopwatch using discrete 7-segment displays.
2) Replace the 7-segment display with a 16-character alphanumeric display.
3) Replace the 16-character LCD with a graphics LCD module
4) Display a photo image on the graphics LCD module.
