LED helper methods
Represents a simple LED
Represents an LED bar graph composed on multiple LEDs
Represents an LED whose voltage is limited by the duty-cycle of a PWM signal.
Represents a Pulse-Width-Modulation (PWM) controlled RGB LED. Controlling an RGB LED with PWM allows for more colors to be expressed than if it were simply controlled with normal digital outputs which provide only binary control at each pin. As such, a PWM controlled RGB LED can express millions of colors, as opposed to the 8 colors that can be expressed via binary digital output.
