Servo angle protractor

Measure and set servo angles

Lay the disc on the servo with the output shaft through the centre and fit the horn on top: the horn points to the engraved angles from 0 to 180 degrees, so you can centre a servo, check its real travel and set end stops before building it into a robot arm.
