Thanks to Marcus Olsson for this tip! “A friend of mine, Balázs Suhajda pimped his bike wagon using trinket and neopixels to improve the visibility. It is really dark in Sweden wintertime.”
Slightly improved the visibility of our bike wagon using an Arduino Trinket and NeoPixel LEDs. 🙂
In this version one has to press a button to activate it. In the next version I plan to have a accelerometer & a light sensor to do it automatically.
