Description
This project is meant to regulate the RPM of my drill which is mounted as a drill-press.
For better performance on low RPM a magned and a hall-effect sensor were placed on the motor spindle inside the drill and not on the output shaft.
The hall-effect sensor enables arduino to count RPM which are then fed into a PID formula and converted to actual number for phase-shift controll circuitry.
NOTE: other then what you see on the diagram you will need a 5v power supply for the circuit.
The GyverTimers library is taken from alexgyver.ru.
