// Latched Rotary Swtich to Momentary Out for Centroid BOB Jog Controls. 
//DIP Switch is replacing rotary latched switch in this example.  
//Press play button on simulation and select switch 1-3 to see momentary output.
//Momentary low output set for 500 ms for representation.
//Input from rotary (DIP) switch remains low, only one momentary pulse until switch input to Arduino is changed and provides another momentary output.
//LEDs are for visual representation only, pins 5-7 would connect directly to BOB Inputs for Jog select speed.
