Ruby in my yard!
summary
Replaces a clunky 20‑year sprinkler timer with a networked controller that actually tells time, fetches weather and runs irrigation rules using Raspberry Pi running Ruby. Drives real 24V solenoid valves through a solid state relay and a Pi T‑Cobbler, wired on a breadboard, demo opens and closes valves live. Uses the gpio gem for pin control, notes Ruby compilation time and that the Pi boots fast; shopping list and instructions appear after the build.
