Not so sure ashugtiwari.
If the door is left open after the LED has timed out, the 555 is still held under power.
I need the timer to disconnect from power after its cycle.
Perfect Betwixt. Thanks!
I will give it a go.
What value would you use for the LED resistor for a simple white 5mm LED?
I am also presuming to shorten the "On" time I just need to reduce the value of either of the RC network?
Thanks ashugtiwari and betwixt.
I should have mentioned that this needs to be low cost, small and simple.
Betwixt, are you able to suggest a circuit diagram I might try?
My tech skills and understanding are moderate so simple works for me :).
I am building a battery powered device (preferably 6v from 4xAA’s) that will drive about 5-10 bright LED’s for 10-15 seconds when a door is opened.
When LED’s power off I would like power to be automatically disconnected altogether so there is zero residual current.
There should be a trigger...
