…Tinkering eventually lead to making this full blown home automation system based on open source hardware (Arduino) and open source software (OpenHAB). I know I know, yet another “Arduino Home Automation” project, right? But I promise I’m not going to turn on a light from a smart phone. I’m more focused on extensive networked sensors, timely alerts, and aesthetically appealing presentation of events.
Here’s the basic idea. With Arduino, it’s really easy to connect boatloads of cheap sensors. Using this setup, that boatload of cheap sensors can now be on the internets. They can email you when things get too hot, too cold, too smokie, too gassy, or too bright. And your dog can email you by barking. You can also view the status of sensors on your smart phone. These sensor nodes are wireless, so you’re not constrained by the location of ethernet ports.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
