Description: Simple electronics simulation of color mixing using an RGB LED. The intensity of the 3 internal LEDs is controlled by
3 potentiometers, that vary the voltage across the LEDs. It is supposed that the voltage variation is directly proportional to the LED intensity and that this
LED intensity proportionally corresponds to a given RGB value. Thus if the first and the third poti are set at the maximum resistance (the second one being
at 0Ω), the RGB LED will produce magenta light; if they are set at half the maximum resistance, the light produced will be purple.
