The main objective is to design and implement a system that can read the temperature of its environment and display it on a pair of 7 segment displays. Also, it should activate a siren when the temperature reaches a specific number that can be changed. Moreover, another task of the system is to activate an LED light based on motion with a certain delay after the motion stops and this delay can be changed. The system should toggle between the previous tasks using a button.
- What sensors will be needed?
- How to read these sensors signals?
- How the System task can be changed?
- How the toggle temperature and the delay time can be changed?
- How to generate this delay?
- How the to process the input signals to output the correct values for the output devices?
