6.4 Microprocessors in control applications
Describe the role of a microprocessor or computer in control applications, including the role of the pre-set value
Describe the use of computer control in applications (e.g. turtle graphics, automatic washing machines, automatic cookers, computer controlled central heating systems, burglar alarms, computer controlled glasshouse)
Automatic washing machines
It is the central processing unit that sends signals to the rest of the machine so that it operates correctly. The washing machine's microprocessor tells the washing machine what to do, based on the selections you make for your laundry, such as the wash cycle and water temperature.
Bugler Alarm
The burglar alarm sensors are connected to a central or control unit that works by sending out a signal when an intrusion, fire or panic was identified.
Burglar alarm signals may be in the form of loud noises. The most advanced burglar alarms systems work by sending signals via the telephone lines or the Internet.
