Hi to All :
Need help on how to build a circuit that will monitor a lamp using a timer ( 3000 Hr timer )
The circuit is about tracking the time the lamp is used.
The purpose is to replace the lamp at 3000 hours used.
The time elapsed should remain when the power is switch off or is lost.
The timer counts only when the lamp is switched on and stops when the lamp is off. The circuit will alarm when the 3000 hours is reached.
The circuit's elapsed time is manually resettable so it can monitor again with the new lamp installed.
My problem is i don't know what kind of timer to use since there are lots of timer available. What are the parts needed?
Thanks for the help....
