Control a Ceiling Fan with 315MHz RF, @Particle Photon, @IFTTT, and Amazon’s Alexa
File this one under ‘things to build this Winter in anticipation of next Summer!’
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”.
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.
