Re: Servo isn't working..!

OK so troubleshooting 101: isolate the problem.

Do you have an oscilloscope? (I seem to remember that your lab is well equipped). If so, you should try measuring the output of the signal pin (don't forget to connect the ground pin to ground!)

are you getting signal?
if you see a square wave signal, that's a good sign already. measure the frequency, it should be between 30-50 Hz. (the signal should have a period of ~20ms to ~33ms).

if you see all that, something is wrong with the servo.

if you don't see any signal -> probably software problem or wrong wiring (Digital side car working?)

if you see a wrong signal
(bad frequency or shape) -> probably software problem

Re: Servo isn't working..!

We just solved the problem actually, from some reason the sidecar didn't work with the servo, so we're fine now. thanks anyway!
