Rotates through 480 steps every time the button is pressed.
Check your equipment to find out how many motor steps it takes for a full rotation. In my case it's 4800. 
4800/sides or gear teeth you need to cut = number to put into "const int pulseset"

const int pulseset = 480; //change this to change how many sides/gear teeth. 4800 pulses per rotation on my spindexer.
const int directionPin = 8;
const int pulsePin = 9; // the stepper driver gives one step at the rising edge of the pulse from the Arduino.
const int sensorValue = 1000; // sets the speed of rotation. 1000 is slow, 10 is fast
