Tell us about yourself!
Yeah. Turned out that u have to calibrate the motor first. Just find a small screwdriver to turn the screw at the center of the bottom of the motor and see what angle works!
Really cool project!! I ran into a problem though...My servo motor doesn't stop spinning even when I set dealy(5000). It stops after five seconds and starts turning counterclockwise really slowly. May I ask if you know how to fix this? Or what variables you used? Thank you!ps. I can't find button L and used button instead (but that shouldn't be a big problem...?)
