A RGB LED is commonly used component in electronics, generally, as it is used for indication purpose. You can use RGB LED in various projects like portable flashlight, LED indicator etc. An RGB LED can also be used for work according to condition like for condition 1st Red will glow, for condition 2nd green will glow and for condition 3rd blue will glow. We can use three different LED to perform the same task but this will increase the size of circuit and took more space on PCB or perf board.
