ESP32 Slot Machine Game (OLED Display + Button + Buzzer)

Pull the lever and watch the reels spin! This **ESP32** project spins three reels of cherry, bell, BAR and 7 icons on a **0.96 inch OLED** with a realistic slow-down, all from one **button**. The credits are purely virtual, with no real money involved: the goal is to learn the **probability** and random numbers behind games of chance. If the first two reels match, the third spins longer for suspense, 7-7-7 plays a JACKPOT tune, and **Preferences** keeps the credits.
