LED

Introduction

The VEX AIM Coding Robot has six LEDs (Light-Emitting Diodes) around the body of the robot. The LEDs can be set to different colors to give feedback, show a robot status, or make the robot easier to track during a project. Each LED can be set individually, or all LEDs can be set at the same time.
