IR Remote Home Control Using the KY-022

//Do what ever you want with this code!
//Again a Multifuntional code, you can control your whole home with it if you want. I made a simple example on how to do this. Good luck!

// i already set extra relays in the code so all you need to do is add them. Right now we have 10 11 and 12 USED, you can add 3 more relays.

//Here we Define the buttons, if you are using a different remote then the HX1838 that i used open serial monitor and press the desired buttons.
//change the numbers you see in the serial monitor here below, and asign a button to that number..
