    ???? Pro Tips:

    1. Look around you: Many of the devices we use on a daily basis are embedded systems, such as smartwatches, home security systems, and even your car.

    2. Pay attention to functionality: Embedded systems are designed to perform specific functions, such as controlling sensors or regulating temperature. When looking for examples, focus on devices that are designed for a specific purpose.

    3. Consider the complexity of the device: The more complex the device, the more likely it is to be an embedded system. For example, a smartphone is not considered an embedded system because it has a wide range of functionalities, but a fitness tracker is an embedded system because it has a specific purpose.

    4. Look for devices with limited user input: Embedded systems are typically designed to function with limited input from the user. For example, a thermostat has a few buttons for input, but the majority of its functions are automated.

    5. Research industries that heavily utilize embedded systems: Some industries, such as aerospace and automotive, heavily rely on embedded systems for their products. Look into these industries for real-life examples of embedded systems in use.
