In this Instructables, we will use a Particle Photon (Arduino compatible) microcontroller coupled with a 315MHz RF Transmitter to send commands to a Harbor Breeze ceiling fan. We will then learn how to use an Amazon Echo and Alexa to activate our fan using voice commands. The ultimate goal is to be able to turn on the fan by saying: “Alexa, trigger fan on”.

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.
