14. Putting Our Plan Into Flowol

15. The Mimic
Lamp
Light Level

16. Simulating Temperature Control
Room temperature
Electric fire
Cooling fan
Too cold (<10) ON
OFF
Just right(10<>20)
Too hot(>20)

17. Matching a Flowchart to a Scenario
When the temperature in the house drops below 10 degrees C, turn on the fire, if it goes above, turn it off.
When the temperature in the house rises above 20 degrees C, turn on the fan, if it goes below, turn it off.

18. Electric Fire / Cooling Fan

19. Using procedures to build an efficient program
Design a system to help a person with impaired hearing in his or her own home.
Consider how you can make sure that the person knows that:
• someone has rung the door bell;
• the smoke alarm is sounding.
How will the person know the difference between these two sounds?

20. The Main Task
Devise a control program that will use the light bulb to differentiate between the smoke alarm and the doorbell, using subroutines to increase efficiency.
