Hello everyone please can you take a look at this coding which is reading two 12 volt car batteries as the end readings showing on the serial monitor are not as accurate as the voltage reading i am getting from my voltmeter, thanks Voltage Divider Calculator <<< Use 10K for R2, 3.3V for the output V's. With Bluetooth built-in, you can see everything you need on the. Use it to monitor voltage, current of a single battery bank, power, state-of-charge and time-to-go.
