I've got some problem with RC servo.
I'm using a servo which I bought from Sparkfun. https://www.sparkfun.com/products/9064
Since it requires 5V voltage and lots of currents, I have to use a external power for servo.
I've followed the instruction on http://learn.adafruit.com/adafruits-ras ... r/overview.
I used a 5V phone charger instead of battery.
When I connect the signal cord to raspberry pi, servo kept running until it reached the maximum angle, even before I issued the python code to control servo. Now, I cannot figure out why it is like this.
Does anyone have an idea?
Thanks a lot.
BTW. I've tried this under both the latest Wheezy and Occidentalis firmware, same result.
