Han , I think you have a slight misunderstanding of the command fd(motor). This command means START running the motors, not continue running the motors. When you hit the switch you need off(motor). So: void main (void) { fd (0); fd (1); printf("Hey, (...) (28 years ago, 21-Jan-99, to lugnet.robotics.handyboard)
