Arduino based stroboscope inspired by this youtube video: https://www.youtube.com/watch?v=WSZ6QDU-eXY
This version makes use of the timers of the Atmega328p and a rotary encoder for the rpm selection.
Tested on UNO and Pro Mini.
- rotary encoder with appropriate capacitors + resistors on the the signal pins
- led flashlight (modified with external cable to your circuit)
- transistor to switch the flashlight
- TM1637 7 segment displays
With minor modification you can print the rpm to serial instead.
