In this chapter you will
Create and test a simple infrared receiver
Remotely control Arduino digital output pins
Add a remote control system to the motorized tank we created in Chapter 12
As you’ll see, with the addition of an inexpensive receiver module, your Arduino can receive the signals from an infrared remote and act upon them.
Although most people use infrared remote controls in a variety of daily actions, they don’t know how they work. Infrared (IR) signals are actually beams of light that operate at a wavelength that cannot be seen by the naked eye. So when you look at the little LED poking out of a remote control and press a button, you won’t see the LED light up.
IR remote controls contain ...
