/*
 * NoPartsBatteryGuageAVR.c
 *
 * This is a simplified demonstration of how to detect power supply voltage by using the on chip 
 * analog-to-digital converter to measure the voltage of the internal band-gap reference voltage. 
 *
 * The code will read the current power supply voltage, and then blink an LED attached to pin 6 (PA7). 
 *
 * 1 blink  = 1 volts <= Vcc < 2 volts	(only applicable on low voltage parts like ATTINY84AV)
 * 2 blinks = 2 volts <= Vcc < 3 volts
