I have recently purchased a Pixy2 with a pan/tilt kit and assembled it. It was working for 15 minutes or so (using Pan/Tilt demo in PixyMon) but then the unit started to shake continuously whilst powered via USB. I removed power, re-checked everything but could not find any problems. I found that if I removed the connection to the pan servo that the shaking stops and the tilt servo operates correctly in tracking vertical movement of objects, just not horizontal movements. Re-connecting of the pan servo causes the shaking to restart. I have also noticed that the unit becomes quickly hot, presumably from the ongoing rapid movements.
- I am using the USB cable included with the official Pixy2 pan/tilt kit to power the unit, not some 3rd party cable.
- Given that I have confirmed that the tilt servo is working as expected, I am sure that the servos are plugged into the correct spots on the Pixy2 board.
Any other suggestions I can try?
