Simple LED Torch

This is a simple LED torch. The specialty of this circuit is this circuit helps to operate your torch for maney hours. Here I have used 2w LED. Throught this circuit you can light up your torch about one month. Here I have used a common IC 7555. This circuit operates with 6v But if you like to operate this circuit with 9v or 12v you have to change R3. If you use 9v use 470 Ohm and if you use 12v use 560 Ohm



 







Note


* Build this circuit on a PCB
* Don:t use NE555 instand of 7555

* Use alkaline bbatteries
