| − | The task is to produce a Flowcode flowchart that lights a lamp for ten seconds when a switch is pressed.<br />
| |
| − | Although it may not be realistic to use a microcontroller in such a straight-forward application, it illustrates the technique of producing a Flowcode program.<br />
| |
| − | The program itself may form part of a bigger program.
| |
| − | The flowchart sequence will be:
| |
| − | : 1. 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.

| − | * Accept the default settings by clicking on 'OK'.
| |
| − | : An empty flowchart window opens, which may contain other items such as a [[System Panel]], [[Dashboard Panel]], [[Properties Panel]] etc.
| |
| − | : These can be revealed or hidden using the [[View]] menu.

| − | * Set up the flowchart window so that you can see the System Panel and the Properties Panel.
| |
| − | : The flowchart window should resemble the one shown below (depending on the configuration.)

| − | * Drag and drop a 'Loop' icon between the Begin and End icons.
| |
| − | : The 'Loop' icon makes the microcontroller repeatedly run through the program, (though the icon can be configured to limit the number of times this happens.)
| |
| − | * Inside the loop, drag and drop an 'Input' icon from the Icons toolbar,. (See [[Tools and Views]].)
