Our milliohm meter works on the principle of Ohm's Law. the working principle and the circuitry are very simple, as you already know from the title, we are going to use an Arduino to process the ...

Learn how to build a DIY current and voltage meter using Arduino Nano. This project demonstrates step-by-step instructions to measure current, voltage, and wattage with precision. Using simple ...

The next line of code is used to set the reference voltage. The V cc is the most important variable in this project to detect the battery voltage. To set the V cc, first connect the Arduino with the ...

With hopes of “making an engineer’s life easier and safer,” Mauer solved this problem using an Arduino Pro Micro and a BLE module to show data from a Bluetooth-enabled multimeter.
