Description

Instructions at https://littlebits.cc/projects/lockout-buzzer This logic circuit is commonly used in a gameshow scenario where each contestant has a buzzer to press to give the answer to a question. Think Jeopardy or Double Dare. The person who presses their buzzer first gets the first chance to give an answer. The awesome thing about this circuit is that the logic gates make it impossible to cheat. When one person buzzes in, the other contestant's buzzers are disabled. This is especially useful in situations where two people might buzz in at what seems like the same time, but one person is actually nanoseconds ahead! Project Application: Make a Spit Game card console using lockout logic! Spit is a card game that involves slapping a pile of cards at the end of each round. The objective is to slap the smaller pile so that you run out of cards and eventually one pile will be empty. The person who slaps the empty pile wins the game. If you are familiar with the card game, Spit, you might know that it can be hard to tell who slapped the pile first. If you'd like some background you can read about it here or watch this video. Using lockout logic and some carefully placed light sensors, this smart Spit console is able to tell who slapped first, and plays a custom victory tune on synth to prove it! littleBits makes a library of open source modules that snap together with magnets for prototyping, learning, and fun.
