When the servo reaches the on or off position, it continues to wiggle quite a bit. I suspect the analogReads still aren't stable even with the delay after updating the position.

  1. Verify with debug mode enabled that this is the case
  2. Test with an external power source as well
  3. Check the analog signal on the scope
  4. Fix it!

Maybe some filtering is a good idea as well:

There are definitely spikes in the 5V line when the servo moves, which makes sense. A 470 uF capacitor on the servo connection practically solves it, no need for software changes just yet.
