Simon Says

Michi Says 🎮 (ESP32 Simon Game)

📖 The Story

This project began with my son Michi, who wanted a memory game.I instantly remembered the classic Simon game from the 80s — the one with glowing buttons and catchy tones. It felt like the perfect father–son project.

There was just one catch:I was new to ESP32 development and new to 3D printing.

That made it the perfect learning challenge. I could build something nostalgic and fun, while teaching myself electronics, coding, and design along the way.

So “Michi Says” was born — a modern, DIY version of Simon, powered by an ESP32, wrapped in a custom 3D-printed enclosure, and built around big, satisfying arcade buttons.

✨ Features

Four 60mm illuminated arcade buttons (bright and clicky, perfect for kids’ hands)
