In this video, I build a simple solar tracker circuit that automatically rotates a gear motor to face sunlight. The circuit uses basic components like LDRs (light sensors), NPN transistors, and a 3V motor. Perfect for beginners learning analog electronics or renewable energy projects! Components Used:
- 2x D882 NPN transistors
- 2x LDRs (Light-Dependent Resistors)
- 3V gear motor
- 100-ohm resistors (2x)
- 9V battery
How It Works:
- When sunlight hits one LDR more than the other, its resistance drops, turning on the corresponding transistor.
- The activated transistor powers the motor in one direction, rotating the panel toward the light.
- The feedback resistors lock the circuit in one state until the light balance changes, preventing motor jitter.
Key Features:
- No microcontroller or coding required.
- Automatically tracks light direction.
- Uses affordable, easy-to-find components.
- Bidirectional motor control with simple analog logic.
