Serial Servo HATs and Raspberry Pi, Arduino expansion boards 3:15 pm October 2, 2023 By Julian Horsey While building robotics projects, the importance of controllers and motors cannot be overstated.

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.

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.

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light.

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 ...
