Appendix: Libraries
The majority of the required libraries are uploaded within the Arduino IDE with other libraries available through GitHub,
www.github.com
, or specific websites as listed in Table A-1. Example sketches, within each library, are accessed in the Arduino IDE by selecting File ➤ Example ➤ library name. A library is included in a sketch with the instruction #include <libraryname.h>, which references the library located in the Arduino IDE libraries folder. To determine the location of the Arduino IDE libraries
folder, select File ➤ Preferences in the Arduino IDE, and the libraries folder is located in the sketchbook location, for example, C:\Users\user\Documents\Arduino.
When a library is included in a sketch, a variable
