DIY Arduino power/energy meter



Best & Fast Prototype ($2 for 10 PCBs): https://www.jlcpcb.com
Thanks to JLCPCB for supporting this video.

Months back we have build a current meter. Now, the last emter tutorial, we calculate power and print it on an OLED display. This project will measure current, voltage, power and energy. I’ve used a shunt resistor for the curent measure. More info below.
