/* 	After uploading:

	You should see the onboard BLUE TX LED flashing
	on each ‘analogRead’ and then see the value of
	the potentiometer's A0 voltage value on the screen.
	NOTE: With a 10K pull-up resistor the output 
	needs to multiplied by 10 to indicate voltage 
	at input A0 in millivolts: 2590 mV = 2.59 Volts, etc.
