We Are Learning To Understand the term control and program § To understand the basic symbols used in Flowol §

What I am 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
