He built a servo tester and demonstrator based on an Arduino, and went the extra mile to give it a good UI and a bunch of functionality.

The proposed idea is a general-purpose tiny toy bot uses two Micro Servos work with an Arduino microcontroller. In this “differentially-steered robot” design, the Arduino is configured to control two ...

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...

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.
