We made the SB-Firefly as a ATtiny85-based blinky light / "chewing-gum & duct-tape problem solver", that is also Digispark shield compatible. We also made the Star Controller 3-watt RGB LED kit as an easy way to tame bright and power-hungry LEDs.

We put them together with a 3-day* power supply and diffusing container, add a 10% savings, and TaDAAAH: The Northern Lights Bundle! And it's well documented too! With version 2 of the SB-FireFly we've also updated the code to include a new "Rainbow" mode, perfect for color shifting through all the primary and secondary colors! It also now has the ability to save modes. If you ever unplug it and bring it elsewhere, plug it back in and it stays in the mode you originally set.

If you'd like to make this bundle into a night light and keep it on mains power, we recommend hooking it up to a 5V power adapter which conveniently plugs right into the 2.1mm jack and you'll never worry about batteries again... It's almost like we planned it that way.

What do you get in the bundle?

• 60140 SB-Firefly kit
• 60160 Star Controller RGB 3-watt LED kit
• 52242 2.1mm barrel jack/plug pair
• 17020 3AA battery holder
• 8025 diffusion container
• Double-sided tape
• 5-conductor wire

Start with our instructions to build a mobile blinky-dome of doom (mount it on your bicycle helmet - everybody will see you coming), or modify it. The SB-Firefly is programmable with the Arduino programming enviroment (with a suitable in-circuit programmer), so you can use the remaining 2 available I/O pins to blend it into your project!

*Northern Light will blink for 3 days when in Regular Firefly Mode with fresh Duracell Alkaline batteries from Costco. 

This is a demo of the new code for Northern Lights Bundle called Rainbow which is designed to smoothly color cycle an RGB LED. See code in Documentation tab:
