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.

In this case, the sensor detects the impact of the speed bag and sends a signal to the Arduino Uno ... The tutorial covers everything from the components needed to the step-by-step assembly ...

We know that measuring the speed ... as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino running ...

Here is a motor speed sensor ... transmissive optical sensor used here consists of an infrared light emitting diode and a phototransistor. This both prevents interference from stray external light ...

I made this project because I wanted a way to automatically control the speed ... sensor. I had a few problems with the PWM part mainly because the fan made a disturbing noise so I had to add a simple ...
