* hungry. The green LED, at full power, consumes more power than the whole chip in active mode,
* and the red LED consumes about twelve times as much power! The LED's should thus be used only
* sparingly in order to preserve battery life.
* @note Some watches use a red/blue LED instead of a red/green LED. You will be able to determine this
* easily when you double tap the reset button: if the pulsing bootloader LED is red, you have a
* red/green edition; if it is blue, you have a red/blue edition. For red/blue watches, build your
