R..R..Iot - Ruby and the Internet of Things

on YouTube ↗25m

" summary

Prototype connects a Raspberry Pi camera + reed switch to GPIO, uses raspistill via system call (because Ruby camera libraries lag), runs wiringpi to read pin state, takes a photo when the sensor opens, uploads the file to Google Cloud Storage and posts the image URL to Slack. Demo runs live from an SD-card Raspbian image; enclosure is Lego; proof-of-concept works. Notes: Ruby requires shelling out or thin gems for some hardware (Python has broader library support); resin.io recommended for deploying Docker containers to many Pis.
