LiPo Battery

<h3 >Read battery voltage </h3>This example shows you how to read the actual battery voltage on a MKR Zero board. The value coming from <code >analogRead()</code> 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 <code >analogRead(ADC_BATTERY)</code> into the corresponding voltage. The sketch below demonstrates how to do it.
