Maker and developer Rolf Hut has created an awesome Arduino powered longboard which is equipped with LEDs that react to the speed of the rider and board.
Hut has used 4 x magnets and a Hall effect sensor to measure the longboard’s speed which is then relayed to the Adafruit NeoPixels setup can react at the same pace and change the colour and display of the LEDs accordingly
Check out the video below to see the Arduino powered longboard in action. The official Arduino website explains more :
To achieve this, the magnets are glued to the inside of each wheel, while a Hall sensor counts the number of revolutions and sends that information over to one of two Arduino Micros. The first Arduino translates that into a speed, while the second Micro converts that speed into a signal for the LEDs. Everything is powered by a power bank.
