Battery Monitoring #11

Open GitM3 opened 2 years ago

GitM3 commented 2 years ago

A simple way to monitor battery life through Arduino: Analog to Digital Converter. 1) Input battery voltage through 10k resistor (current protection) 2) Compare to [analog reference voltage] (https://www.arduino.cc/reference/en/language/functions/analog-io/analogread/) 3) Reference voltage can also be determined by measuring between Arduino's 5V and gnd. (Mine is 4.85 V for some reason) 4) ref voltage * (analog count)/1024
