This simulation demonstrates how an RGB LED can generate different colors by varying the input signals applied to its red, green, and blue terminals. Each LED channel (R, G, and B) is driven by a square wave signal with different phase shifts but the same frequency of 1 kHz. The waveforms at the top show voltage variations for each color — red, green, and blue — switching between 0V and 4V. By adjusting the duty cycle or timing of these square waves, the LED mixes the light intensities of the th
