I have a plan to build my own electronic compass for my sailboat. The idea of spending $500 on something I can make myself (while learning new things) just seems silly. I started this project with the Adafruit ARDX – v1.3 Experimentation Kit for Arduino. It comes with a lot of components which teach you quickly how to use the Arduino IDE and board in a variety of types of tasks. Here you can see I’m playing with 8 green LED and the micro servo that was included in the kit. Frankly I’m blown away at how simple they make these kind of experiments.
