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 ...

This project used the XBee Pro Module to transmit and receive signals wirelessly, and an Arduino UNO executed all given instructions. The presence of the car was identified by an infrared sensor, also ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

Once you have all your components, you can start assembling your high-speed camera trigger. Connect the piezoelectric sensor to the Arduino, and then connect the Arduino to the camera and flash.
