Arduino Advent Calendar Day 10 - IR Remote!
Today we're going to take command of your Arduino with an infrared remote control!
What is Infrared?
Infrared is a wavelength of light that is longer than visible light. You can't see it, but if you shine an infrared remote control at your computer's webcam you'll see it doing a little blinking sequence!
What is Infrared Remote?
An infrared remote is like a flashlight that sends coded messages in the Infrared.
Your Arduino, paired with an Infrared Receiver (and some software) can decode the signals sent from your infrared remote. In our Sketch we can branch our logic depending on what signal is received. E.g. turn on a pin if one code is received, and turn off the same pin if another is received.
Enough talking about it let's go and build up the circuit over at guides.littlebird.com.au .
