This Arduino sketch monitors the voltage output from a potentiometer connected to analog pin A0. It displays the voltage reading on the serial monitor and controls two LEDs based on the voltage level.

This project measures real-time voltage and current from a DC load using an ACS712 Hall-effect current sensor and an analog voltage divider connected to an Arduino. The data is read by the Arduino’s ...

In my last blog post: http://embeddederic.blogspot.c… I took an Adruino Uno and a Protoshield and made a simple battery monitor, so I could measure the voltage of a ...

This Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...

The goal of this project is to develop a highly accurate current-voltage monitor that only costs a few euros and should also be universally applicable. To ensure that the circuit can be used ...

While those of us stuck sailing desks might not be able to truly appreciate the problem, [Timo Birnschein] was tired of finding that some of the batteries aboard his boat had gone flat. He wanted some ...
