Im still very new to electronics and this is my first time making an application project, so i decided to make a game buzzer. I've found on the web a buzzer circuit but i need to do some modifications. So the reset switch must be replaced with the 10sec timer w/ 7segment display.
this is how it works when a trigger switch is pressed it lights the corresponding LED, sounds the bleeper and prevents the other trigger switches from working but i need to make a 10 second countdown timer with 7segment Display , after the switch is pressed the countdown starts and after ten seconds the buzzer switch can be pressed and used again.. I need it to have a 555 timer if possible. please help!! thanks very much!
I've attached the buzzer circuit diagram. :
