hi,
I want to create a simple time delay circuit, I was thinking with a 555 timer or something similar.
The issue I have is that I am modifying an existing circuit which means it has some built in contraints:
Trigger Voltage: ~1V ( I don't know if this will be enough to trigger the timer)
Trigger Duration: 0.5 - 1 second
Circuit Voltage source: 4.5V (if need I can use a higher voltage source and use a pair of resisters to step down the voltage to the 4.5v part of the circuit.)
Output Duration: ~10-15 seconds
any advise would be great, thanks
