Need to put a colorful light on a costume, hat, model or project? Look no further!

Powered by 2-AA batteries, this kit will rotate through the colors of the rainbow in mesmerizing smoothness. It can also pulse in red, blue or green light.

Everything you need to build your rainbow light is included, even the battery case!

• 1 - High Quality Lead-Free Professionally Printed Circuit Board
• 1 - Pre-Programmed ATTINY13 Microcontroller
• 1 - Bright Multicolor Red/Blue/Green LED
• 1 - 2-AA Size Battery Holder with 6" Leads
• 1 - 2 Pin Header
• 1 - Assembly and Operation Instruction Sheet

Complete online assembly instructions!!

Each part is clearly labeled on the printed circuit board for easy assembly. Soldering is required. All of the components are standard easy-to-work thru-hole type. Paper instructions for assembly and operation are included with each kit.

If you bridge the two pins with a paperclip, the lights will cycle from rainbow -> red -> green -> blue -> sleep -> rainbow. You can add you own external switch too! Just add a momentary push button switch between the "sw" and "g" pins.

It is quite easy to integrate this into your own project. The LED can be wired from the board to a location away from the battery and board.

This entire kit, hardware and firmware is designed and packaged by myself, a professional engineer, in the USA. I would be happy to answer any questions you might have.

I almost always ship the same day or the next day an order is placed.

I also offer a combined shipping discount if you order more than one kit! Just add them to your cart to see the shipping price.

Please look in my listings for other kits I have designed.

Thanks so much for looking and have a great day!

P.S. Select the "Fully Assembled" option if making is not your thing, and I'll put it together for you myself!
