“I’ve been learning about IR protocols for quite some time now. How to send and receive IR signals. At this point, the only thing remaining is the IR protocol of AC remotes. Unlike traditional remotes of nearly all electronics devices (say a TV) where only one button’s information is sent at the time, In AC remotes all of the parameters are encoded and sent at once. Hence, It can be a little bit tricky to decode the signal from a microcontroller. In this instructable, I’ll Explain how we can easily decode IR protocols of any AC remote. I’ll be using my HID IR KEYBOARD to read and decode the IR signals by writing a new program. but you can use nearly any microcontroller you’re familiar with as long as it supports External interrupts coupled with a TSOP IR demodulator.”
