Microprocessor Control Applications
Features include:
Wired / wireless internet connectivity – so that they can be monitored, controlled and updated over the internet. They have a number of input ports, so that they can be connected to buttons and sensors.
Output ports, so that they can turn on motors, devices or alarms. The use usually low power devices, meaning they down use a large amount of electricity, especially in standby mode.

Washing Machines
We don’t think of washing machines as computers, but modern washing machines contain a microprocessor that controls all of the complex washing cycles that modern washing machines have.
Inputs

Preset Values
The dial on the front of the machine has a number of preset values:
The washing temperature
The cycle type (eco, intense, soak)
The spin speed
Automatic Cookers
Automatic cookers are becoming increasingly popular, especially for those people who want to eat quality home-cooked food, but work full-time. They can be used to cook a variety of meals and foods, including: Slow-cooked stews Pies, Pastries and Bread Rice
Output
The cookers turn on and off the heating elements The cookers often also output a sound or tune when the food has finished cooking
Preset Values
The cooking temperature
The programme type ( what type of meal is being cooked)
Start time / delay so food only starts cooking at a certain time.
Burglar Alarms
Burglar alarm systems have become increasingly popular, and now have a vast array of different sensors and control devices.
Central Heating
Central heating systems now include increasingly complex micro-processing units. Modern systems can be controlled via an app on your phone, or even control themselves through location and behavior monitoring.
Outputs
Turn on the boiler
Close automated windows and vents
Preset Values
Temperature setting on the dial Heating on/off times
