Building a Wearable Simon Game With Conductive Fabric

If you've ever wanted to turn a classic memory game into something you can actually wear, this week's spotlight is for you: the Wearable Simon Game Video Kit. It's every part I used to build the game in my Wearable Simon Game video, packed into one box — and as of this week there are only 4 left in stock. I'd rather explain why it's worth grabbing than just slap a 'low stock' banner on it, so here's the real rundown.

What's actually in the box

This build centers on an ESP32, a set of WS2812B addressable LEDs for the classic red/blue/green/yellow sequence, and conductive fabric pads sewn directly into the wearable so your taps register as real switch input — no bulky buttons required. Everything is matched to what's on screen in the video, right down to the wire gauge, so there's no guessing or substituting mid-build.

Why it's a genuinely good project to learn from

I designed the Simon Game build around three ideas I come back to constantly when I'm teaching: state machines, input debouncing, and timing. The game logic has to track an increasingly long sequence, listen for the right input at the right moment, and forgive a slightly-too-slow tap without losing the plot. That's a compact, satisfying way to practice concepts that show up in almost every interactive project you'll ever build — long after you've moved on from Simon Says.

And because the input is conductive fabric instead of a mechanical button, you also get a hands-on lesson in why e-textile connections behave differently: resistance changes with pressure and contact area, so your debounce logic needs a bit more tolerance than it would with a clean digital switch. It's a small wrinkle that teaches a big lesson.

How you'd actually use this

A few ways I'd put this kit to work beyond 'because it's fun' (though it is genuinely fun):

• Classroom or workshop demo: it's a self-contained way to show state machines and sensor debouncing without a lecture slide in sight.
• Portfolio piece: if you're building out a wearable tech portfolio, a working game people can actually play at a demo table is worth more than a still photo of blinking LEDs.
• Gift for a maker friend: it's scoped tightly enough to finish in an evening or two, which matters more than people admit when picking a gift kit.

Why it's limited

Some of the components in this kit — particularly the conductive fabric cut to the pattern used in the video — are sourced in small batches, and I'd rather sell out honestly than overpromise stock I don't have. If you want to build along with the video, now's the time. If it sells out before you get to it, keep an eye on the listing; I restock kits based on demand.
