After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

The sensor sends “hit” signals to a small Arduino Uno via a PC817 optocoupler. The headcount is then displayed on a small LCD screen positioned above the speed bag, allowing you to keep track ...

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.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
