I'm using this product: Overview | Adafruit PowerBoost 500 + Charger | Adafruit Learning System for powering my Arduino Micro.
Now, when there is no power to the Arduino board (By connecting EN & GND of the powerboost together) - the 5V and GND pin are both LOW. I have the LBO (Low Battery Output) connected directly to a digitalPin on the Arduino. This is usally HIGH or LOW - which the Arduino will read once turned on. My issue is, when the EN & GND are connected to turn off the Arduino, the RED low battery light illuminates on the powerboost board, because LOW is floating around the board. Can anybody think of a solution? Or do I just leave the red light constantly illuminated while it's turned off? I just don't really want to leave the RED LED on, and over a period of time drain the Battery.
