Step 17Test

Now that you're done assembling it, you can test the board to make sure its functioning. Put two good AA batteries into the clips. Whenever the microcontroller gets notice of a 'hard reset' it goes through a little test routine where it lights up all the LEDs in order. If none of the LEDs are lighting up, go back and check to see if you put in any latches, batteries or the microcontroller in backwards. If just a few LEDs arent lighting up, check if they're in backwards.

If you still don't get the top of the wheel moving at 120, go watch a tracked vehicle (bulldozer, tank) drive by. The bottom of the track that is in contact with the ground is stationary with respect to the ground while the top of the track is moving forward at twice the ground speed with respect to the ground.
