Bluetooth LED Pinewood Derby Car
My son is in the Cub Scouts and wanted to build a "Star Power Mario Car" for the pinewood derby. There are a lot awards other than fastest that you can pickup so I decided to go for style points. I used a Tinket, Bluefuirt and Neopixel strips from Adafruit and basically combined this and this tutorial. It worked great for the judge but during the actual race the neopixels weren't working. I think didn't have enough power going to them.
Here's a video demoing what we built:
