You can install through the Library Manager, click to the "Sketch" menu and then Include Library > Manage Libraries.

Find OpenDevice and click <Install>

Install from source

To install the library, you can simply clone the repository: opendevice-lib-arduino 

git clone https://github.com/OpenDevice/opendevice-lib-arduino  OpenDevice

And put in the "/libraries" folder of the Arduino IDE.

Remember that some examples in this library need extra libraries that must be downloaded and enabled in the configuration file: dependencies.h
