Re: How do the servos work?
essentially, when you output 1, you told the servo to rotate almost as far as it can in one direction (almost, because the minimum is 0, but there's little difference). thus, outputting 0 wouldn't make it come back, only turn a fraction more in the direction it already was.
dead center would be outputting 127. try that.
likewise, to make it turn in fully the other direction, output something towards the upper end of the range, such as 254.
