Controlling analog inputs with the wiring-x86 library

So far, we have been using the mraa library to work with analog inputs and retrieve the ambient light level. However, we have also been working with the wiring-x86 library in our previous examples. We can change just a few lines of our object-oriented code to replace the mraa library with the wiring-x86 one to read analog values.

First, we have to replace the code for the AnalogLed class with the version that works with the wiring-x86 library. We created this version in Chapter 4, Working with a RESTful API and Pulse Width Modulation, and the code file for the sample was iot_python_chapter_04_04.py. When we grab the code for the AnalogLed class, we will also have the Board class.

The following ...
