In this video I build a simple Solar Street Light Circuit that turns ON automatically at night and turns OFF during the day. Perfect for beginners — this project uses a BC548 transistor, LDR (light dependent resistor), 1KΩ resistor, and an LED.
🔧 Parts used:
BC548 transistor
LDR (Light Dependent Resistor)
1KΩ resistor
LED
Small wires / solder (optional)
💡 How it works:
During daylight the LDR has low resistance so the transistor keeps the LED OFF. At night the LDR resistance increases, the transistor switches, and the LED lights up automatically. I demonstrate wiring, soldering tips, and live day/night testing.
