The Keyestudio Solar Tracking Kit teaches renewable energy and control systems in one project. Four light sensors compare light levels around the panel, and two servo motors tilt and rotate the panel so it always faces the brightest source. A lithium power module stores the energy and can charge a phone through USB. The kit starts with lessons on testing each electronic part, then guides students through assembling the tracker and loading the final program.
