Want to make your solar panel automatically follow the sun? 🌞 In this video, I’ll show you how to build a simple light‑tracking circuit with just a few components – a TDA2822 audio amplifier IC, two LDRs, a DC motor, and a 3.7V battery. The circuit compares the resistance of the two photoresistors and drives the motor to keep the panel perfectly aligned with the light source.

I walk you through the wiring, assembly, and even the working principle (two voltage comparators with opposite phases). Perfect for beginners in electronics or anyone looking for an affordable solar tracker project. Schematic included at the end – feel free to DIY your own version!
