Installing Arduino Libraries

The Experimenters Guide uses IRLib2, an easy-to-understand Arduino library that de-mystifies the infrared light receiver. It makes writing code for IR Reciever and IR LED much easier.

Installing the IR Library 

To install the IR Library:

  1. Download the IR Library by clicking the button above, or download it directly from the IRLib 2.x Library from Github.
  2. Uncompress the ZIP file after it’s finished downloading.
  3. Check that the uncompressed folder contains five separate folders. IRLib 2.x contains multiple libraries that work together. 
  4. Copy all five into your Arduino Library folder root directory. The path will typically be in (home)/Documents/Arduino/Libraries. If you do not see the /Libraries/ folder, you may need to create this yourself. 
  5. Restart the Arduino IDE.
