This handheld Blackjack game uses an Arduino Nano, a 1.3" 128x64 I2C OLED display, and a four-button interface. It features card animations, a betting and bankroll system, 2-to-1 Blackjack payouts, double down bets, and other player-friendly details.
I tried to make this project as compact and user-friendly as possible. It uses only six data pins and no resistors are needed.
Note that the OLED panel uses the SH1106 display controller, which requires a different library than SSD1306 panels. You can download the library here.

I turned the project into a true handheld with a small LiPo battery and USB-C charging. It's a lot of fun. Overall dimensions are about 4-1/8 x 1-7/8 x 3/4 inches.
