One channel of LSDj controles one servo the other channel controls the other servo.. Originaly the idea was to send good pwm signals to the servo.. This did not work for me.. But just sending it audio frequencies works o.k. enough.

The idea was that it crawls forward, this did not work.. So now i just used it for drumming instead. Will see if i can make it move in a direction later..

The circuit is power by external power supply, using a 6v voltage regulator and a 5v voltage regulator.
