It will be simple. I started to look at the sketch of the Arduino Robot and just tried one, Disco_Bot, and uploaded it one the top board. The Arduino started to play some music and the name was on de LCD screen but he wasn't moving. Then i tried then sketch Wheel_Calibration. The information was on the screen but the Robot was supposed to move so that i could calibrate the speed. I was lost so I went on the Arduino page for the Arduino Robot (http://arduino.cc/en/Guide/Robot) and found nothing that could explain my problem . So now I ask you, can you please help me because iI have no idea on what i should do.
