Some time ago I got into decoding an infrared AC remote with the purpose of controlling the AC via WIFI.
I learned a ton of things along the way and I wanted to share that knowledge with all of you in case it can help you in future projects (future-me: I’m looking at you too).
I used a Particle Photon but you may choose to use a different MCU since the IRremote Arduino Library (from Ken Shirriff) used in this project supports plenty of others. Here’s also its official page.
There is a lot of information on that page, make sure to read some of it for a deep understanding of how IR signals work, but I’ll reproduce some important points in the next section.
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.
