This simulation demonstrates the working of an RGB LED driven by different input signals to produce multiple colors. Each of the three LEDs inside the RGB package—Red, Green, and Blue—is powered through separate signal sources that generate triangular waveforms. By varying the intensity of each color through these waveforms, the LED mixes them to create different color outputs. For example, turning on only the Blue section gives blue light, while combining Green and Red produces yellow, and acti

This simulation demonstrates the working of RGB LEDs driven by three sinusoidal AC sources at 1 kHz frequency. Each source powers one LED—Red, Green, and Blue—through a current-limiting resistor of 100 Ω. The current waveforms for the LEDs are shown at the top, where the red, green, and blue signals vary sinusoidally and independently. As the currents flow through the LEDs, the RGB light components combine to produce varying colors depending on the instantaneous current in each LED. This illustr
