Programmable Rainbow Light Up Sign - Microbit

With my [original sign project](https://www.thingiverse.com/thing:3051648) I set out to design something to make with my kids and their friends when they visited [Cambridge Makespace](https://makespace.org). I wanted it to involve laser cutting, 3D printing, electronics and a bit of science. The project was a success and we've made loads of them, however, I wondered if I could also involve a bit of programming and make the signs battery powered plus my kids wanted rainbow lights and so this project was born.

The laser-cut acrylic sign portion of the design remains unchanged from the original but the 3D printed case is expanded to fit in a battery pack, power-switch and BBC Microbit. Plus as programming is more fun with inputs I added a hole for a button at the front of the case.

There are example Micro Python programs [here on my github](https://github.com/burrowsa/microbit-projects/tree/master/Colour%20Sign)
