Automatic street light or night light is the solution for those people who forgot to switch off their home lights in the daylight when light is not necessary.when the light is available the lamp is switched off & when the light is not available the light is automatically on.In this video I will show you how to make an automatic night light using transformer-less power supply.To make this project a few & easy components are required
Components lists
1. 1uf/400v capacitor
2. 1 megaohms/1watt resistor
3. 1 100ohms/1watt resistor
4. 220ohms/1watt resistor
5. 470uf/16v capacitor
6. 5*1n4007 diodes
7. 1 led
8. 12v/1watt zener diode*1
9. 1k/.5 watt resistor*1
10. 100k resistor*1
11. 2*bc547 transistor
12. LDR*1
13. 12v,1c/o relay*1
14. 220v bulb
15. bulb holder
16. breadboard/pcb board
17. connecting wires
miscellaneous items
cutter,soldering iron,plastic box,electrical tape etc
