Todd Treece has put together seven guides using Adafruit IO for input, temperature, humidity, servo control, and so much more:
The Adafruit Learning System is also a great place to find learning guides which answer the age-old maker question of "what do I build next?".
Here are some of our favorite guides using Adafruit IO:
Build an internet-enabled environmental monitor to see what's in the air you breathe using Arduino
Learn all about home automation by building a cardboard smart-house, controlling its lights, and monitoring temperature!
Build a simple home automation system & control it from anywhere!
Build a camera that detects motion and sends images to cloud services like Dropbox & Adafruit IO!
The Adafruit Blog is also a good resource for finding your next project. Check out the Adafruit IO blog posts here!
