The RGB LED block and JD's eyes contain 18 RGB LEDs (54 LEDs in total).
They plug directly into the EZ-B v4 Smart Robot Controller and each LED's color and brightness can be adjusted individually within animation sequences!
This activity requires either a JD Humanoid or 18 RGB LED Block and will help you learn how to program the RGB LEDs.
What You Will Need
JD with a charged battery or 18 RGB LED Block
Windows PC with ARC (formerly EZ-Builder) installed
