Got Python I/O: IoT Development in Python via GPIO
summary
Shows you can build a working IoT device with pure Python and GPIO using cheap hardware and Linux file ops, not special drivers: the GPIO sysfs interface via /sys/class/gpio file interface is enough to export pins, set direction/value/edge/active_low and toggle LEDs or relays. Uses Raspberry Pi (~$30 or Pi Zero $5) or Intel Edison for heavier crypto, and Twisted plus WebSockets for evented networking. Demonstrated a door lock that a Python weekend build replaces months of C work and a six hour robot prototype.
