I Built a Pocket-Sized Arduino Game Console (And It’s Actually Playable)

Tired of blinking LEDs and basic sensor projects? Same here. So I tried something different. I built a handheld Arduino game console that actually runs real games, fits in your pocket, and feels surprisingly fun to use. What This Project Is About This isn’t just another Arduino demo. It’s a fully working mini game console powered by an Arduino UNO R4 WiFi, paired with a small OLED display and a few buttons. The goal was simple, build something interactive, not just functional. And honestly, it turned out better than expected. The Idea Behind It Instead of building separate small projects, I wanted one device that could do multiple things. Games felt like the perfect choice. So I packed 10 classic-style games into a single system. Think Snake, Pong, Tetris, and a few more, all recreated to run smoothly on limited hardware. Not exact arcade versions, but close enough to feel nostalgic. The Hardware Setup The hardware is simple but cleverly arranged. Everything sits on a custom HAT-style
