  • Bought two of these. Hooked up to the Uno’s PWM output, they seem to be calibrated for 0-180 PWM output on the arduino which is nice since it is a 180 degree motor. The problem I have with one of them is it only moves about 160 degrees and when 0 is sent to the PWM output, it looks like it is binding inside and draws a lot of current. Could some of these be manufactured with the pots off a few tens of degrees? This would be acceptable if the motor did not have physical rotational constraints at 0-180.

No public wish lists :(
