I will start with the PCB design of the dispenser unit with enhanced debouncing (one with CD4093) coming monday, since that is the one that best suits my application.
I will let you know about it.


How about you design, build and test it ? That's how we learnt. If it doesn't work, ask again, but the experience of failure is valuable and teaches importnat lessons.
