Examples
LEDs can be wired either active high or active low. The LED components should each have a property allowing you to configure which LED type your using.
An active high LED will light when the microcontroller pin is outputting a logic 1 and be off when the microcontroller pin is outputting a logic 0 or in input mode.
An active low LED will light when the microcontroller pin is outputting a logic 0 and be off when the microcontroller pin is outputting a logic 1 or in input mode.
The series resistor can be on either side of the LED and acts to protect the LED from damage due to excess current. The value of resistor used can be changed based on the brightness of the LED and power consumption.
This LED Calculator tool is a good resource for calculating the correct LED series protection resistor.

Simulation |
|
Color |
| The color of the LED when it is turned on. | |
|
Trim Leads |
| Trim the length of the two leads. Length cannot be less than 3.0, or greater than the length as supplied. | |

Label |
|
|
Show |
| Decide what labels to show... None - no labels are displayed Name - shows each component's name Property - shows a particular property of each component (see 'property' below. | |
|
Property |
| Show a particular property of each object. If a port or pin property is chosen, the label can be abbreviated to remove the '$PORT' text. | |
|
|
Color |
| Color of the labels text. | |
|
|
Scale |
| Sets the basic size (text height) of the labels. | |
|
Follow Zoom |
| Whether labels get bigger and smaller when the panel is zoomed in and out. | |
|
|
Position |
| Position of the label relative to tehe component | |
