Yes we used a spike!
It would be.... interesting to try it with a speedcontroller. I was talking about the fan inside the compressor. I assure you we tested every piece betwean the control board and the compressor and every one works! We just can't get the spike to get a signal from the boards relays (Tried multiple (MANY multiple) pwm cables). Its unlikely its the code because it stoped running while we were using it. We have to ship the robot to Capitol Clash tomarrow. Any help will be really usefull.
