How to Make Solar Tracker Using TDA2822 IC | No Arduino DIY Project

In today's video, I show you how to build an incredible Automatic Solar Tracker system from scratch! ☀️⚡️How to Make Solar Tracker Using TDA2822 IC | No Arduino DIY Project. I created a solar tracker system that automatically follows the sun's movement. The solar panel rotates on its own to always face the sun directly, maximizing energy capture without manual adjustment. This interesting DIY project uses a TDA2822 IC for precise control, along with two LDR sensors, two potentiometers (tank resistances), a gear motor, and a battery for power and storage. Key Components & Circuit Design The TDA2822 IC serves as the core differential amplifier, comparing light levels from the two LDRs positioned on opposite sides of the panel. When one LDR detects stronger sunlight, the IC outputs a signal to drive the gear motor, smoothly turning the panel toward the optimal angle. Potentiometers adjust sensitivity for different lighting conditions, while the battery powers the system and stores excess solar charge for later use. This analog circuit eliminates the need for microcontrollers, keeping it simple and cost-effective. Project Benefits 1.Boosted Efficiency: Tracks sun for 30-40% more power generation than static panels, ideal for charging devices or running lights. 2.Affordable Build: Total components under ₹500, perfect for school science fairs or home renewable energy experiments. 3.Reliable & Educational: Teaches sensor-based automation; durable for outdoor testing. Components Required: 1.IC: TDA2822 (Audio Amplifier IC) 2.Sensors: 2x LDRs (Light Dependent Resistors) 3.Resistors: 2x 10k Resistors (or similar values) 4.Motor: DC Gear Motor (High torque for moving the panel) 5.Power: Rechargeable Battery & Solar Panel 6.Misc: PCB or Breadboard, connecting wires, soldering kit Join this channel to get access to perks: https://www.youtube.com/channel/UC00rSCnbZHfkfi7LFhO1CYg/join
