An Arduino controlled chess clock.
The speed of the clock can be changed with a potentiometer.
High speed for reaction games.
t is the delay after each change of levels and allows the magnetic fields to build up properly. t=3 works for most stepper motors. Make sure your power supply is accurate and supplies 5 volts, 1 or 2 Amps. The Arduino sketch below makes it all work.
//Nano half step mode
//512 >> 360 degrees 1.4 step/degree
int Pin0 = 9; int Pin
