Embedding Ruby into your Daily Life
summary
Claim: Ruby can run on microcontrollers by using Mruby runs in ~80KB RAM and cross‑compiling Ruby into bytecode that gets linked into C for upload. Tools: Raspberry Pi and BeagleBone Black handle high‑level state and web UIs, Arduino (ATmega328p) or Due handle realtime IO with I2C delegation, and mrbc produces bytecode for an Arduino‑hosted VM. Surprises: 8KB AVR SRAM is too small for CRuby, one Arduino Due can host Mruby, a rover and brewery PID controller and a “Keep Me Alive” plant warden all actually work.
