Control TechnologySTART
What is control
technology?
What is this diagram called?
In which program have you used these before?
Lets Go!
Lesson Objectives
• To understand – what control technology is – What flow charts are, including their individual components
– How flow diagrams are used everyday in control technology systems
Control Technology
• Control technology is allows devices to be programmed to respond to different circumstances
• A good example of this is a kettle. A sensor will record the temperature of the water. When the water is boiling, the kettle automatically turns itself off.
• Can you think of any other examples?
Prior Learning
• You have already studied Control Technology in year 7 using Crocodile
• You should already know how to use flow charts

Switch kettle on
Boil water
Is the water at boiling point?

Terminator – Starts the flow diagram
Input/Output – If you are doing something to
trigger a reaction (INPUT), or the
reaction that occurs (OUTPUT)
Process: When an action is being carried out.
Decision: Asks a question and has 2 responses (YES/NO)
Terminator – Ends the flow diagram
Task 1:
• Flow Chart Symbols
• Go to Common K>ICT>Year 8>FLOWOL> Lesson 1
• Open and Save the file called “Flow Chart Symbols”
AnswersSymbol Name Description
Terminator Starts and stops the flow chart
Process When an action is being carried out
Decision Asks a question and has 2 responses
(YES/NO)
Input / Output
If you are doing something to trigger a reaction (INPUT), or the reaction that
occurs (OUTPUT)
Arrow Shows the flow of data in the flow
diagram
Flowol
• Go to Start>All Programs>Flowol
• We will be using this program to simulate how control technology is used in everyday life
Mimics
• In Flowol there are several mimics that you can use. These are simulations that we can control using flow diagrams.
• Click USE MIMIC >Zebra Crossing
This is the mimic/simulation
The different inputs and outputs that we can control appear
here. In this simulation there is only one light.
Task 1:
• Drag and drop the symbols on the left to make the light flash on and off.
Task 2:
• What is wrong with the simulation?
• How can we make it better?
1.Add a delay between the flashes
2.Loop it around so it happens continuously.
Extension:• Save your zebra crossing in your Unit _ Folder
• Open a new flowol document and open the Crossing Patrol mimic.
This time you have 2 outputs to control. Try and make them flash on and off simultaneously
