I am new to hardware and among the things I got to get started I purchased a servo:
I haven’t been able to incite a response from the servo using any of the write methods in the servo lib, and I know the servo isn’t dead (and that it is powered) as I can get a response by taking the sensor wire and tapping it against it’s own input wire, it only jumps at the beginning of the tap – holding it against the live wire does not incite a sustained response.
I also know my code is running since I can make the main LED blink arbitrarily in the loop.
I know this question is a little vague, are there any obvious things I might be doing wrong?
EDIT: if it helps at all, I am powering the servo with 2 AA batteries on a separate breadboard
I had it wired like this:
battery (+) -> servo power
battery (-) -> servo ground
servo signal -> sparkcore (D0)
