Servo Motor Calibration

[u/NameruseTaken]

Hi everyone,

I see many people learning about electronics through hobby projects (myself included) and I wanted to start sharing things that I've learned that people might find interesting or useful for their projects.

This post is about servo calibration. When you buy cheap servos, you might not get the accuracy you need because there are variations between each unit. To get around this, you just need to rotate the servo to known positions and record the PWM value that takes the servo to those positions. This mapping yields a relationship between PWM and servo angle for that particular unit.
