The IotDevice class

The IotDevice class will contain the specific behavior for our sensor node. This class will contain the methods necessary to sample our sensors, control external devices, and so on. For our example, the IotDevice class will perform several functions, including the following:

• Manage the state of the LEDs (which represent the external devices to control)
• Manage sensor variables, such as temperature and humidity
• Hold the IoT device's ID
• Include methods for sampling and controlling the IoT device

The first step is to create the IotDevice class and build the constructor. An example of what this might look like can be seen in the following code:

class IotDevice:    def __init__(self):        self.LED1 = "Off"        self.LED2 = "Off" self.LED3 ...
