I'm making a delay timer for my camera.
However, i'm having a trouble coming up with a circuit to sort my problem out.
Basically, I need a circuit, where the output is low.
Once a a trigger signal has been recieved, it waits for the delay period (adjustable from 1ms to 1 second) to elapse, then puts the output to high for a period of 20ms.
I have thought about using a 555 timer in monostable mode, but I can't get my head round the fact it needs to be low, once triggered, still low until the delay period has elapsed.
ideally, I need it to be simple as possible. Although using a PIC microcontroller is looking more suitable solution.
Any advice?
