This code depends on the previous configurations already defined in the configuration.h file (such as the definitions of ports and pins for the switches and sensors).
What does this code do?
This code handles interrupts from two groups of devices:
Override Switch: Allows changing the manual control state (enable or disable).
Manual Switch: When manual control is enabled, this switch allows opening or closing the door.
Motion Sensor: If the sensor detects motion, it closes the door; if not, it opens the door.
Infrared Sensor: If the sensor detects presence, it activates the alarm; if not, it deactivates the alarm.
Why does it do this?
The purpose of this code is to manage various input devices (switches and sensors) that affect the system's behavior (open/close door and activate/deactivate alarm). Interrupt handling allows these actions to be performed efficiently without blocking the main flow of the program.
How does it do this?
Reading switches and sensors: It uses interrupts to detect changes in the switches and sensors. When an interrupt is detected, the state of the switch or sensor is read, and an action is taken.
Notifying tasks: If the manual switch is enabled, the code notifies the tasks to open or close the door based on the manual switch state. For the motion sensor, the door opens or closes based on the sensor state.
Activating alarms: If the infrared sensor detects something, it activates the alarm; otherwise, it deactivates the alarm.
