DescriptionFastest Finger First Quiz-type game shows are so popular on television these days. In such games, the Fastest Finger First Indicators (FFFIs) are used to test the player’s reaction time. The player’s designated number is displayed with an audio alarm when the player presses his entry button. The circuit presented here determines to which of the four contestants first pressed the button and locks out the remaining three entries. Simultaneously, an audio alarm and the correct decimal number display of the corresponding contestant are activated.
This Fastest Finger First Kit can be used for a quiz with up to 3 contestants (or teams). Each contestant has a trigger push switch and LED. When a trigger switch is pressed it lights the corresponding LED, sounds the bleeper, and prevents the other trigger switches from working - therefore showing which contestant was the first to press their switch. A reset push switch (operated by the quizmaster) cancels the bleeper and switches off the LED so the circuit is ready for the next question.
