Minecraft, Dead By Daylight minigame question [closed]

I have a question about a game I am creating. In the game people have to make 5 devices activate and how I plan to do this is they have to click a button 100 times with the command, /scoreboard players add 1. My question is how can I sense when 5 different devices are done and have it affect the game by giving strength and destroying/adding buttons?
