Hi everybody,
I want to build a precise driver circuit.
Whenever i'm measuring 5v it should give some indication(led flash,beep sound.etc..)
if the input voltage is in between 4.8 and 5.2v, then only my circuit will drive led or beeper.
if the input voltage is not in the above range,then the driver circuit should not work.
I'm having a simple transister switching circuit but the tolerance is very high.if the voltage is exactly 5v(4.8-5.2)then only i need some external indication.my driver circuit is giving output even for 3.3v.
Waiting for a reply,
Thank u.
