I've been working on a project where I've to drive the servo motors. I am using Raspberry Pi 3B+ model and Adafruit PCA9685 to drive the servos. For that I need to find which angle is at what pulse length and really been stuck here for a while. Any help would be appreciated Thanks!!

A pulse width of 1500 µs moves the horn to the centre. You can call that any angle you want, say 0.

For each 10 µs decrease in pulse length the servo moves one degree clockwise.

For each 10 µs increase in pulse length the servo moves one degree counter clockwise.

These figures are approximate and vary by servo model.

The servo will have angle limits. If you try to move a servo beyond its limits you can damage/destroy the servo.
