I am having issues with my Arduino Uno controlling a small servo.
When i load the servo sweep-knob sketch it works fine the first time, however if i alter the code, for example changing the maximum angle in the mapping function, the software says uploading, and then just hangs, i get the following error message - avrdude: stk500_recv(): programmer is not responding.
I cant even forcequit the arduino application and have to hard restart my macbook pro.
I am running Mac OSX 10.5.8. and the servo is a SM-S2309S
Does anyone know why this may be? The whole purpose i bought the arduino was to control servos and solenoids so its rather frustrating.
Yours sincerely, Patrick M. Keenan
