DIY AUTOMATIC ON/OFF 12V LIGHT WITH RED & GREEN INDICATOR #shorts #ytshorts #ledlighting #electronic

In this video, learn how to make an automatic 12V light control circuit using an LDR (Light Dependent Resistor), BC547 transistor, resistors (1K & 33K ohm), red & green LEDs, and a 12V relay. This circuit turns the light ON at night and OFF during the day automatically, with indicator LEDs to show the status.

🔧 Components Used:
✔ LDR (Light Dependent Resistor)
✔ BC547 NPN Transistor
✔ 1KΩ & 33KΩ Resistors
✔ 12V Relay
✔ Red & Green LEDs
✔ 12V Power Supply

📌 Working Principle:

When light falls on the LDR, the resistance decreases, turning the relay off and switching off the light.

When it's dark, the LDR resistance increases, activating the relay to turn on the light.

Indicator LEDs show the status of the circuit.

🔴 Red LED: Light is OFF
🟢 Green LED: Light is ON

💡 Perfect for:

Automatic street lighting

Home & garden lighting
