 ## Multiple Inheritance
 Multiple Inheritance is used to inherit the properties of multiple classes. However, Python does not allow multiple inheritance from classes that have incompatible memory layouts at the C level, which is common with hardware classes in MicroPython.

 ### Setup differnet states of the controller using association
 
+In the context of a microcontroller, state refers to the current values or conditions of the system’s internal variables, inputs, outputs, and memory at a specific moment in time. State is crucial for determining how the microcontroller should behave next.
+
+For example, in a simple traffic light controller, one of the states could be `Traffic_Go` in which the green lights are `on()` while both the red and amber lights are `off()`.

 ## Open & Closed Loop Control Systems

+A home thermostat works by allowing the homeowner to set a desired temperature. The system then measures the actual room temperature and adjusts the heater or cooler to reach and maintain the set temperature. As the system approaches—or overshoots—the desired temperature, it modifies its output accordingly.

 - States: Distinct modes or conditions in which the system can exist.
