I am building a BoE-Bot and thought it would be fun to attach a camera on to it. I bought a pan/tilt kit from here:
It came with 2 HiTec hs-422 servos.
I used my "testservo.bs2" program that I create in my "What is a microcontroller?" lesson (chapter 4 I believe).
I connected one servo to servo plug 14 and the second servo to servo plug 15. Attached is my program. I pretty much have both servos sweep left to right. The odd thing is that after the program ends, one of the servos always steps little by little to the right - as if its getting a quick shot of PULSOUT 15, 1000, but over and over. I wondered if it was the servo pin I was using, so I switched them. No matter what, its always the same servo - no matter what pin I plug it into.
I used a parallax standard servo and got what I thought was "normal" behavior. The second HiTech hs-422 servo behaves fine as well.
Does anyone have any idea why the servo would behave like this after the program has finished running?
