Our Adafruit IO library for Arduino was recently updated to include lots of new features. We especially like this guide which integrates If-This-Then-That with Adafruit IO to build a door-detection circuit to email/tweet at you if somebody opens a door.
The code in this guide has been edited to be compatible with the new changes to the Adafruit IO Arduino Library.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
