21 or Bust
Automatic Blackjack Dealer
Shawn Nishimuro, David Gandionco, Ed Torres, and Tim Petrie
Need all the action and lights of Las Vegas? The 21 OR BUST automatic blackjack dealer is made to imitate real Vegas blackjack dealers. Utilizing light-sensitive photoresistor sensing, it accurately reads cards, deals them out face up/face down accordingly, play the dealer’s hand, and even tells you if you bust or beat the dealer. Depending on the card value read, a sequence of motors is initiated to deal the card out correspondingly.
