JavaScript for Hardware

on YouTube ↗33m

" summary

Shows tiny microcontrollers running JavaScript with Espruino and a Chrome web IDE, live-coding a working torch that saves the interpreter image to flash and runs standalone. Demonstrates setWatch interrupts for buttons, serial/USB hacks to send events to a PC, and power measurements: sleep at ~3 microamps versus active ~20 milliamps for bursts. Compares to Raspberry Pi battery life, mentions cheap ESP8266 boards at ~$2, and sketches a Nokia LCD + digital temperature sensor build that actually displays readings via uploaded JS.
