ICT APPLICATIONS PART3

6.4. Microprocessors in control applications

LEARNING OBJECTIVES

• 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)

INTRODUCTIONS

In control applications, sensors send data to the microprocessor or computer to store incoming data value.

The microprocessor/computer will take some action which will ultimately affect the next input value it receives. By the action, they control the application.
