I was following Gaven MacDonalds video (https://www.youtube.com/watch?v=ddlDgUymbxc) on getting a servo running off the pi. I got overambitious because I managed to get an LED or two to blink! I got a cheap Analog Servo with a bundle from Radioshack last night and decide to try it with that. I followed the directions right up to the PWM steps. When I ran it, for the first couple of cycles it seemed to go ok, then all it started to go faster.
I had a larger servo, a Tower Pro SG-5010. I plugged that in. When I ran the program with this, it did the first 7.5 pulse then restarted the pi.
What did I do wrong? Any clues?
