About this project

Read battery voltage

This example shows you how to read the actual battery voltage on a MKR Zero board. The value coming from analogRead() is converted into voltage, and printed out to the serial monitor of the Arduino Software (IDE).

On the MKRZero there is an analog pin called ADC_BATTERY for this purpose. You only simply have to convert the analogRead(ADC_BATTERY) into the corresponding voltage. The sketch below demonstrates how to do it.
