In this project, you’ll build a monitor that measures the current (the flow of electricity) generated by your solar panel. You’ll then convert this measurement into a visual display on your micro:bit, showing you how much electricity is flowing in real-time!

A small solar panel and circuit board assembly, featuring a micro:bit current monitor, is connected to an external device via a white USB cable.
