An IR remote and receiver communicate with each other by transmitting and decoding a signal in the form of pulsed IR radiation. Infrared radiation (IR), or infrared light, is a type of electromagnetic radiation with wavelengths ranging from 700 nm to 1 mm. Because humans can only see light with wavelengths of roughly 400 (violet) to 700 (red) nanom...
It is very easy to hook up an IR receiver to the Arduino as you only need to connect three wires. The output wire can be connected to any of the digital pins of the Arduino. In this case, I connected it to pin 2 for the first examples below. The supply power pin is connected to 5 V and the middle ground pin to GND. If you are using a receiver that ...
For this tutorial, we will be using the popular IRremotelibrary. This library is fairly easy to use and supports many different types of IR remotes. To install the library, go to Tools > Manage Libraries (Ctrl + Shift + I on Windows) in the Arduino IDE. The Library Manager will open and update the list of installed libraries. You can search for ‘IR...
NEC is probably the best known and most widespread IR transmission protocol as it is used by the vast majority of Japanese-manufactured consumer electronics. However, many other types of protocols exist. It can be useful to known what type of IR protocol your remote is using if you want to work on more advanced projects. Or you might just be curiou...
Because there are many different types of remotes on the market (with different number of keys and key functions), we need to determine which received signal corresponds to which key. The IRremote library will read the signal and returns all information about the signal in the following structure: We are especially interested in the commandpart of ...
Now that we know which code corresponds to which keypress, we can modify the code to print the name of the pressed key in the Serial Monitor. For this, we will be using a switch casecontrol structure. This lets us execute a different piece of code depending on which key is pressed. The code example below prints the key name in the Serial Monitor in...
The following example can be used to print the pressed key values on a character LCD. I have written a detailed tutorial on using character LCD displays which you can find here: 1. How to use a 16×2 character LCD with Arduino If you prefer to use an I2C LCD that needs fewer connections, see the tutorial below: 1. How to control a character I2C LCD ...
Although it’s fun to see the key values in the Serial Monitor or on an LCD display, you will probably want to use the remote for something more useful, i.e. actual control something. In the following example, I will show you how to toggle LEDs on and off with the remote. You can also use this type of code to control relays, lights, and motors. The ...
In this tutorial, I have shown you how to use an IR remote and receiver with Arduino. We looked at several different code examples for determining the IR protocol and identifying the IR key codes for your remote. We then looked at displaying the key/button values in the Serial Monitor and on a 16×2 character LCD. Lastly, I showed you how to control...

26. Feb. 2015 · Installation of the IRLib library is as follows: Visit the IRLib2 page on GitHib. Select the “Download ZIP” button, or simply click this link to download directly. Uncompress the ZIP file after it’s finished downloading. The resulting folder should be named "IRLib2-master" and will contain 5 separate folders.
