Step 17: Control system

Picture of control system
This is a small thing but I soldered 320 Ohm resistors to each end of the carbon track of each 10K potentiometer. This stops you sending too much current through microcontroller input pin by accident which might possibly damage it. There is a webpage on the net about this somewhere on the AVR tutorial websites and similar forums.
