  1. Control Technology START What is control technology? What is this diagram called? In which program have you used these before? Lets Go!

  2. 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

  3. 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?

  4. Prior Learning • You have already studied Control Technology in year 7 using Crocodile • You should already know how to use flow charts

  5. Flow Charts Terminator Process Decision Data Arrow

  6. Terminator – Starts the flow diagram START Input/Output – If you are doing something to trigger a reaction (INPUT), or the reaction that occurs (OUTPUT) Switch kettle on Boil water Process: When an action is being carried out. Is the water at boiling point? Decision: Asks a question and has 2 responses (YES/NO) N Terminator – Ends the flow diagram Y End

  7. Task 1: • Flow Chart Symbols • Go to Common K>ICT>Year 8>FLOWOL> Lesson 1 • Open and Save the file called “Flow Chart Symbols”

  8. Answers

  9. Flowol • Go to Start>All Programs>Flowol • We will be using this program to simulate how control technology is used in everyday life

  10. 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

  11. This is the mimic/simulation The different inputs and outputs that we can control appear here. In this simulation there is only one light.

  12. Task 1: • Drag and drop the symbols on the left to make the light flash on and off.

  13. Task 2: • What is wrong with the simulation? • How can we make it better? • Add a delay between the flashes • Loop it around so it happens continuously.

  14. 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
