Hello all, this is my first post so please be gentle with me.
I have a 555 timer in a monostable configuration. I needed it to be able to not retrigger itself if the trigger button was held longer than the pulse the 555 generated. So i incorporated an RC circuit to do this. It's a very common way of doing this from my research. You'll see a diode also on the trigger line in series. This is required in my setup to prevent high voltage spikes blowing up the 555. It works well for this purpose, i haven't blown one up since incorporating this diode.
My issue then is that sometimes when lifting off the button after holding it down longer than the 555 output pulse, the 555 will trigger again. In my circuit this can not be allowed to happen.
I have tried a lot of little things but sadly i am simply out of electronics knowledge to be able to fix this issue by myself.
