Detailed explanation-1: -Embedded systems in a washing machine, for example, would include closing and opening of valves to let water through into the system at set intervals (pre-wash, washing) and then out when it needs to drain. These processes are controlled by microcontrollers.
Detailed explanation-2: -Computers have been integrated into home appliances of all types, including dishwashers, refrigerators, dryers and washing machines. The microprocessor unit in your washing machine controls sensors, valves and actuators responsible for controlling the parts that clean your clothes.
Detailed explanation-3: -Depending on the embedded system’s purpose, they use input devices like sensors and switches to produce output, for example sounding warning buzzers and switching lights on.
