In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield.
Step 1: Materials
After getting your boards and battery, the Arduino IDE will be the first thing to download if you have not done so already. When the IDE has been loaded go to tools, board, and select Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328.
