Hello Everyone!
I am a novice with circuits and want to get better with analog in particular. I want to build a lockout buzzer system wherein after the host pushes a button the contestants are allowed to push their buzzers, then the first buzzer to be pushed has an LED light up for that contestant, but all other buzzers that were pushed after this did not register (their LEDs do NOT light up).
This is a pretty simple concept and after looking up schematics online i am pretty sure it wouldnt be too hard for a novice like me to build. But so many of the things I have read use an arduino. Is there a way to build this system without a microprocessor?
My first instinct was to use PFETs that connect to every buzzer except the designated player. So when player 1 pushes their buzzer, it activates the PFETs from the each other contestant making open circuits and thus not lighting up their LED. The only problem is then this doesnt stop someone from pushing their button and activating the PFET on the first players buzzer....
Is there a simple way to build this with analog parts? Or is the microprocessor basically the only way?
