Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions ...

I have a standard servo that can rotate approximately 180 degrees (90° in each direction) and is controlled using the included Arduino’s Servo Library. The code is simple too and I’ll try to explain ...

An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.
