Initial Ideas for Blackjack Game
• Create a digital and portable blackjack game
• Explore the capabilities of Qprox sensors and try to
emulate the hand motions of a real blackjack game
Ideas for Revising Game
• Include push, double down, splitting, and bidding
• Show card face values rather than card value totals
• Change functionality of the ace card to determine 1
or 11 value
• Possibly give player tips through audio
Problems During Implementation
• Multiple LCD Screens
– Multiple PICs and Passing multiple-character string variables
– Multiplexer - No documentation, time
– “Buggy” LCD displays
