Circuit 4C - Heads Up Game
|
||||
|
||||
This is a DIY version of the popular Heads Up party game. To play, one person resets the RedBoard and holds the LCD
|
||||
facing away from them so that they cannot see it (usually on their forehead). The display will show a short countdown
|
||||
then display random words. The other player(s) who can see the screen must yell out clues until time runs out or the player
|
||||
guesses what word is on the screen. If they guess correctly, they can press the button on the breadboard and another word
|
||||
will be displayed.
|
||||
|
||||
This sketch was written by SparkFun Electronics, with lots of help from the Arduino community.
|
||||
This code is completely free for any use.
