LEDN

The LED component is an N array of Light Emitting Diode (LED) indicators.

Roadmap: Bind schematic.

Description

The Nth LED is ON when the Nth input pin is driven by greater than 2.5V otherwise the LED is OFF. The color of the LED is determined by the COLOR property. When the LED is ON the LED color is lighter than when OFF giving a visual clue to voltage level at the LED input pin. LEDs are a fundamental indicator of circuit status.

The voltage is considered a Boolean HIGH/LOW and the light is ON or OFF. PWM Fading is not modelled.

SPICE

The LED Pins are modelled as a Standard Diode ( 0.7V voltage-drop ) in series with 220 Ohm resistor.

Roadmap : Parameterise the resistor and voltage-drop.

OpenVBB

The LED Pins are Input Pins where is VAnode == HIGH and VCathode == LOW the LED lights up.

PinOut

Pin	Name	Description
N	Output[N]	DIP Output. Nth Pin is 5V if the Nth switch is On State else is Gnd.

Properties

Property	Default	Description
Cathode	Ground	Determines how the cathode is connected
Color	red	The color of the LED indicator
PinCount	1	The number of pins.

Cathode

The cathode connection is connected either internally to GND or is broken out as a PIN.

Color

Color of LED.

Available Colors:

• Red

• Green

• Blue

• Yellow

Roadmap : Allow any named color.

PinCount

The number of pins in the LED array.
