The Concept

Wear the Game: A Wearable Simon Says Simon Says is one of those games that never gets old. The sequence builds, the pressure mounts, and then you slip up on step seven. Classic. Now imagine playing it not on a plastic toy, but on your own body — with conductive fabric as the buttons and WS2812B LEDs as the feedback.

That's exactly what this build is.

The Concept

This wearable Simon Says uses an Adafruit QtPy ESP32-S3 at its core, with touch-sensitive pads made from conductive fabric as the four inputs. Each pad corresponds to a colour and position in the sequence. Get it right and the LEDs celebrate. Miss a beat and the game resets. Your score is displayed in binary on a strip of LEDs — because of course it is.

Why Conductive Fabric?

Traditional Simon uses hard plastic buttons with a click. This version uses soft, touch-sensitive fabric patches — no clicking, no mechanical parts, no rigid housing. The sensors respond to the electrical capacitance of your fingertip, the same way a touchscreen does, but stitched right into the garment. It's gentler, more surprising, and far more interesting to explain at a party.

It's also a fantastic teaching project. The build introduces conductive fabric, capacitive touch sensing, NeoPixel LED control, and game logic — all in one wearable package that people actually want to play with.

Binary Score? Yes, Really.

The score display uses WS2812B LEDs in binary — each lit LED represents a power of two, so a score of seven lights up three LEDs. It's a subtle nod to the people in the room who'll immediately get it, and a conversation starter for everyone else.
