We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

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 ...

Contains applications of voltage and current measurement with Arduino. The voltage measurement application reads the voltage through an analog input connected in parallel with resistors R1 and R2. The ...
