Memento – a Pocket-Sized Memory Game With ESP32-S3 and Round Touch Display

The maker community continues to push the boundaries of what's possible with compact, affordable electronics. A standout example is Memento, a pocket-sized memory game that combines the ESP32-S3 microcontroller with a round touch display, proving that powerful projects don't need to be large or complex.

Memento is a handheld game device that challenges players to remember and repeat increasingly complex sequences of colors and sounds. The project leverages the ESP32-S3's dual-core processing power and built-in WiFi capabilities, paired with an elegant round touch interface that makes gameplay intuitive and engaging. The circular design isn't just aesthetic, it's functional, allowing players to tap different segments of the display to input their moves.

Why This Project Matters

This build demonstrates how modern microcontrollers have made it possible to create feature-rich devices at a fraction of the size and cost of traditional gaming hardware. The ESP32-S3 brings impressive specifications to the table: fast processing, low power consumption, and the flexibility to handle both game logic and touch input simultaneously. Pair that with a round display, and you've got a device that's as fun to look at as it is to play with.

For makers and hobbyists, Memento is an excellent reference project. It shows how to integrate touch sensing, manage game state, handle audio feedback, and design a polished user experience—all in a device small enough to fit in your pocket.

Key Components

The build relies on widely available prototyping components: the ESP32-S3 development board serves as the brain, while the round touch display provides the interactive interface. The modular design means builders can customize aspects like color schemes, difficulty levels, and even game variations.

Projects like Memento inspire the electronics community to think creatively about form factor and functionality. Whether you're interested in game development, embedded systems, or simply enjoying the challenge of building something clever with your hands, this pocket-sized memory game is worth exploring.
