We Are Learning To • Understand the term control and program • To understand the basic symbols used in Flowol
What Iam Looking For By the end of the lesson you will: • Be able to identify an automatic system • To be able to produce a simple Flowol Program
Automation • An automated system is one that does something automatically. • The kettle switches itself off when it has boiled. • Think of 3 more examples of automation you see regularly
A Program • A sequence of instructions that can be followed to achieve the desired result. • You will use Flowol to write simple programs to control mimics. A mimic is a simulation of a real event
Example • Washing clothes • You select a specific wash programme on your washing machine, e.g. woollens and delicates • the washing machine follows the set of program instructions that correspond to that programme.
Output • Common forms of output • Turning lights on and off • Turning motors on and off • What are the outputs for the following? • Street light • Smoke detector • Burglar alarm
