I’ve always been somewhat unsatisfied with Arduino home automation projects – I wanted a nice mobile platform to display sensor data, collect and chart sensor data, and be able to send email notifications when things like water is detected.
I finally found a wireless transceiver pair and a open source platform that worked well with Arduino. Here’s the project write up. In it, you’ll find wireless fire/smoke sensors, sound sensor, laundry room washer/dryer completion notifier. The platform also can control things like Sonos speakers, z-wave locks, and a couple other commercial smart devices.
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.
