About: I can't be the only person who spend their whole time making stuff and then never using it?!
This machine is controlled by a PicAxe Microcontroller. A servo (used for steering in R/C cars) is used to tilt the track for a ball to roll round. The degree of the tilt can be controlled by a potentiometer in manual mode or in automatic mode preset instructions on the microcontroller tell the servo how to move.
