🎮 Building a DIY Gaming Console Using ESP32

Retro games never get old.

As makers and embedded developers, we usually build IoT dashboards, sensor projects, automation systems, and robots. But this time I wanted to build something different:

A mini gaming console powered by ESP32.

The goal was simple:

✔ Build with low-cost components
✔ Add multiple games
✔ Use an OLED display
✔ Keep it open source
✔ Make it easy for anyone to recreate

The result is a compact DIY gaming console capable of running classic games directly from an ESP32 development board.

🛠 Components Used

This project uses very simple hardware:

• ESP32 Dev Board
• OLED Display (I2C)
• Push Buttons
• Buzzer
• Perf Board
• Jumper Wires
• USB Power

The complete design stays lightweight and inexpensive, making it perfect for:

• Students

🎮 Games Included

The console currently supports multiple games including:

☄️ Asteroids
🧱 Breakout
🦖 Dino
🐦 FlappyBird
🌀 MazeRunner
👻 Pacman
🏓 Pong
🐍 Snake
👾 SpaceInvaders
🚓 Tank
🧩 Tetris

The interface includes a menu system where users can select and launch games directly from the OLED screen.

Even though the display is small, gameplay feels surprisingly fun.
