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

This simulation demonstrates the working of an RGB LED driven by three independent square wave signals applied to its Red, Green, and Blue pins. Each channel (R, G, B) is connected through a current-limiting resistor (100 Ω) to a pulse generator. By switching the three channels at different times, the LED combines the colors to produce multiple shades. The waveforms show 0–4 V pulses at 1 kHz, where the duty cycle of each signal controls the brightness of the respective color. When mixed, they g
