What Is an LED?

<sidebar>Sidebar: What Is a Component?</sidebar> A Light-emitting diode (LED) is a small light which lights up on command, and can be programmed to flash in a pattern and respond to other components etc.

LEDs are commonly used for displaying that a command or event has occurred and is can used to display that a separate component or even a whole system is on/enabled. You can use LEDs to create and simulate applications such as car and motorcycle indicators and change the colour of the LED mid-simulation using a flowchart program.

You can create your own LED or add similar functionality to any shapes and some components using the LED Base to control the connection, polarity and colour of the target when on and off as well as set the default state of your LED.
