Overview Which feature of RGB LEDs has made them an attractive and practical component in Electronics and Lighting Industry?Answer: Their unique feature of regulating the ratio of the three primary colors (red, green, and blue) to generate a desired color with one LED. An RGB LED has a common pin as well as three pins for red, green, and blue colors. We can combine these primary colors to generate countless colors by controlling these pins with a PWM pulse signal. (The number of colors changes depending...
