Arduino Robot Arm

This is a robot arm I made for school. The assembly was quite easy, and the arm worked well. You can find all the parts for a good price on AliExpress. You’ll need an Arduino Uno, four MG996R motors, a motor driver (make sure it’s sufficient for all four motors), a power supply, and of course, some googly eyes. I added a laser pointer to the end of the arm and took long-exposure photos to test its accuracy (I’ve included a picture).This project was a lot of fun, so I decided to share it.
