Versatile multimeter made with Arduino Nano

If you ever wondered about building your own multimeter, YouTuber Electronoobs shows us just how to do so with an Arduino Nano.

Aside from the Nano, he’s using a 128×64 OLED screen to display stats and battery level, and a 16-bit ADC for precise measurements. Power is provided by a small onboard LiPo battery, and he’s even included a charging module to help keep things topped off. Everything is housed inside a custom 3D-printed case.

The device doesn’t just measure voltage, resistance, and current, but is capable of reading capacitance and inductance as well—measurements that you wouldn’t necessarily expect on a commercial meter. If you’d like to create your own, the schematic and code are available on Electronoobs’ site.
