2 player reaction game, player who pushes his button first (whose light turns on), near 555 timer,wins the game. Button near vcc restarts the game (both lamps turned off).
555 are used in bistable mode. output feedbacks npn transistor of other player such that when one player is faster other players light does not light on. (only one player should win)
Edit: trying this out on the breadboard, we discovered that the threshhold signal was floating, so to get the circuit to work, we need to add a big resistance to ground parallel after the reset button.
