Sample code for a no parts, no pins, no power supply voltage detection on ATTINY84
/*
* 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

// with LOW it lgiths up the led and with HIGH it lights off because its INVERTED due to common anode rgb led
