This diagram shows the embedded system inside a microwave oven. The microcontroller is the brain that controls everything. It receives signals from the input buttons when you press them. It also reads data from the sensor (like a door sensor or temperature sensor). The microcontroller sends signals to the display to show time or settings. Finally, it controls the heating element to cook the food. Arrows indicate the flow of information and control signals between parts.

Variations - 2 Challenges

[intermediate] Draw a diagram showing an embedded system inside a digital wristwatch. Include the microcontroller, buttons, display, battery, and sensors (like heart rate). Show connections and signal flow.

[advanced] Draw a detailed flowchart showing how an embedded system in a washing machine controls the washing cycle. Include inputs (buttons, sensors), decision points (water level, temperature), and outputs (motor, valves).
