picked up an analog servo, just up the street!
there is a hobby shop that specializes in models, trains, and *remote control* vehicles, like airplanes, cars, boats…
I’ve been in there many times, and have picked up wooden trains, and tracks, and looked at the train setup in the window; but it only just occurred to me that I could by *robot* equipment there. I’ve been going all the way downtown!
Took a little while to get the Motor Shield working, was not obvious that pin 10 is header 1 (seemed like it should be pin 9)
the servo I have has a range of ~180:
