Learning to build a robot arm will teach you how to breadboard a circuit, how to program your Arduino, and how to work with moving parts.

If you want an easy project to complete in a day or so, or something to introduce kids to the world of robots and electronics, make this light-following robot your weekend project.

The build relies on the classic Arduino Uno microcontroller, which talks to a HC-SR04 ultrasonic sensor module and two infrared sensors in order to track a human target and follow it around.
