can anyone give me a timer circuit using 555 which is working. i found some circuit in the net but some people says its not working. The timer will start as soon as it receives an input on pin 2 of 555 let's say a led on pin 3 will light but when it reaches the specific time let's say 1-10 minutes it will turn off.

You could show a schematic, that would help.

A simple 555 timer actually needs a few more parts than just switching pin 2, though for such a long delay it would work...
