Hi
I`m trying to make a system that :
When a button is pressed, a single short pulse is output - once, no matter how long the button is held for. although the button can be pressed repeatedly, for a single pulse each press.
I`m thinking about using a 555 timer to time the short pulse, and a SR latch to set the timer?
So the button press sets the latch, with outputs a pulse for say 1ms - upon which the timer resets the latch, and disables the button input, until the button is released.
Either can you help with that, as I cant get my head round it, or am I barking up the wrong tree?
