Tiny Computers, JavaScript and MIDI
summary
Claim: web browsers (notably Web MIDI in Chrome) can talk to hardware so JavaScript plus tiny computers actually control real devices. Demos use Arduino and Raspberry Pi, WebRTC to broadcast notes to 71 audience machines, Launchpad MK2 and accelerometer controllers, and node with the MIDI npm package. MIDI messages are literally three bytes per message, virtual MIDI devices work server‑side, and quoted browser support is about 59% global coverage. Built projects include a working interactive audience piano, color mixer, poetry mashup, servo‑driven fake organ and a playable Go board.
