Stop and Go Kit v1

This is a soldering kit that you build yourself! The holes on the base of the stop-and-go light are LEGO compatible so you can build this kit into your various brick projects. You are welcome to create a derivative of this kit as long as it abides by the open source hardware definition.

This kit cycles through a red, yellow, and green LED from an ATtiny85. The code is written in Arduino.

This kit assumes you know how to solder. If not, there are plenty of online tutorials on how to solder. The kit is fairly quick to put together, roughly 10 minutes, and the chip has been programmed for you!
