 * D27 - Single pulse armed pin. toggles the armed state when it recieves a falling signal
 * D28 - Single pulse enable pin (A FALLING signal toggles single pulse mode)
 * D29 - Single pulse trigger. (LOW will cause the arduino to send 1 waveform pulse)
-* D30 - Slow pulse flag (LOW enables a pulse rate of 3 pulses/second)
+* 
 * D31 - Armed state indicator light output
 * D32 - Fired state indicator light output
 * D33 - Operates a relay which isolates the high voltage side of electronics from the electrodes
