IR Receiver (VS1838B)
Decodes button presses from a TV-style infrared remote.
How it works
An IR receiver is a 3-pin module that picks up the 38 kHz infrared flashes from a remote control and outputs a clean digital signal. Paired with the IRremote library, you can read a unique code for each button on almost any remote.
First run a sketch that prints the code for each button you press, then use those codes in your own if-statements.
