 - This information will be contained in a variable called 'switch'.
- Click on the down arrow at the right-hand end of the 'Variable:' box to open the variables dialogue box.
 - Hover to the left of the 'Variables' label and click on the down arrow that appears.
 - Click on the 'Add new' option to open the 'Create a New Variable' dialogue box.
 - Create a new variable named "switch" with initial value "0" and description "Copies the state of the switch"
 - Leave the 'Variable type:' as 'Byte'.

- Finish configuring the input properties as follows:
 
- Change the 'Display name:' to "Read the switch".
 - In the 'Variable:' box, type the name of the variable you created "switch".
 - Leave the 'Port:' as PORT A.
