Question

In operation, questions are read to the contestants. When contestants know the answer, they must buzz-in by pressing their respective button before answering. The first one to buzz-in, causes the Buzzer output to turn on along with the respective Win lamp for 2 seconds. For example, if player 2 is the first to buzz-in, the Buzzer andWin2 outputs will switch on for 2 seconds indicating that player 2 was first. At the same time, players 1 and 3 will be locked out; i.e. their pushbuttons will be disabled until the previous win times out. If two or more players buzz-in at exactly the same time, it doesn't matter which is chosen as the winner, but only one must win (a tie is not allowed). The outputs will stay on for 2 seconds only, even if any or all pushbuttons remain pressed
