How To Check Battery Level With Arduino. Measuring Battery Level. Lithium chemistry batteries hold a voltage quite close to level up to the point of near-exhaustion.
I have used the Arduino boards regulator to make the 5V rail. The calibration for this Arduino 6 LED battery level indicator circuit must be done carefully if you did not calibrate correctly the circuit will show incorrect voltage level of the battery. When you plug the battery to Arduino Vin it should work right away showing the voltage of your battery on your 16x2 LCD because Arduino is powered by that battery.
On the MKRZero there is an analog pin called ADC_BATTERY for this purpose.
Regarding the given answers. Therefore for sensing the voltage level of the battery an integrated circuit is required which can precisely detect the voltage across the terminals of the battery.
