What is an IR library?
The IR library collects the timing information in a buffer and then turns it into a single 32 bit value. You can then easily compare that value to the one you want. Similarly if you want to transmit IR signals, all you need to do is pass 32 bit value to the library and tell it what protocol you want to use.
How do you decode IR data?
To decode the IR Remote Control we use the IRrecvDemo arduino sketch as given with the IR Remote Library. And connect the TSOP1738 to the arduino as given in the circuit. The open serial terminal at 9600 baud rate. Repeat few times and make sure you are getting the same hex value for a single button.
How do you decode IR remote signals?

How do I use Arduino libraries?
The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data. To use a library in a sketch, select it from Sketch > Import Library.
How do I send IR signals from Arduino?
Connect an IR LED to Arduino pin 3 and ground, along with an appropriate resistor, if needed. Depending on your IR emitter’s power output, you may want to implement a transistor for control, though you likely won’t have any issues with short IR signal bursts sent out during experimentation.
What is IR decoding?
I’m talking about an IR decoder/encoder that primarily decodes the invisible data transmitting from an IR remote control handset under test into a perceivable notion suitable for further experimentation/investigation. The same setup can also be used as a “limited” universal IR remote control.
Can my phone be used as a remote?
Google recently launched a new remote-control app for Android phones that lets you control compatible Google TVs and Android TV operating system devices. You can add the remote to the Quick Settings tiles on your Android phone.
Where does Arduino store libraries?
Please note: Arduino libraries are managed in three different places: inside the IDE installation folder, inside the core folder and in the libraries folder inside your sketchbook. The way libraries are chosen during compilation is designed to allow the update of libraries present in the distribution.
Where is Arduino standard library?
On Windows, it would be My Documents\Arduino\libraries\. To add your own library, create a new directory in the libraries directory with the name of your library. The folder should contain a C or C++ file with your code and a header file with your function and variable declarations.
How do I connect my Arduino receiver to my IR transmitter?
IR transmitter interfacing with arduino The connections are similar to the IR receiver module. Connect the 5V and ground of the Arduino to the 5v and ground of the IR receiver and the pin 10 of the Arduino to the signal pin of IR receiver. Library is same for both IR receiver and IR emitter.
