Exercise - Using Component Macros

Component macros are sections of code that have been written to support the components included with Flowcode 6.
They take all the effort out of using these components. This exercise uses them to control a particularly complicated, but very common device, the Liquid Crystal Display (LCD). It uses it to display the elapsed time, once a switch has been pressed

Formulate the sequence

The flowchart sequence will be:

Check if the switch is pressed.

If it isn't, go back to the beginning.

If it is:

switch on the lamp;

wait for 10 seconds;

switch off the lamp;

go back to the beginning.

It takes such a short time for the microcontroller to carry this out, that we don't need to worry whether the switch latches on or not.

Set up the flowchart

• Open Flowcode.

The program 'knows' when you have added a component to the System or Dashboard panel.
