Programmable LED Button Grid for Makers

C5/10March 19, 2026
WhatAn affordable, hackable grid of programmable illuminated buttons designed as a platform for interactive games, visualizations, and creative coding projects.
SignalMultiple people express a strong desire for a programmable grid of buttons that light up in different colors — something they can use to build games, interactive art, and simulations — but find existing options either too expensive, too limited, or repurposed from music hardware not designed for general hacking.
Why NowPCB manufacturing costs have plummeted, capacitive touch sensors can be printed directly on boards, and the maker/STEM education market is booming with platforms like Arduino and Raspberry Pi creating a massive ecosystem of hobbyist developers looking for novel peripherals.
MarketMakers, STEM educators, and creative coders; ~$500M maker hardware market growing 10%+ annually; competitors are repurposed music controllers (Novation Launchpad) or expensive one-offs — no purpose-built, affordable, developer-friendly grid exists.
MoatOpen SDK and community-built library of games/visualizations creates a content ecosystem and switching costs; first-mover in purpose-built category vs. repurposed music gear.
