I am currently working on a project that will control a string (or individual) RGB LEDs. The RGB LEDs I will be using contain separate Red, Green and Blue LEDs in a single housing. Mixing the amounts of current going through these three colors will vary the total color of the LED package. Doing a little research I found out that there are many different ways to control the brightness of RGB LEDs. Here are a few of them: Amplitude Modulation, Pulsed Amplitude Modulation, Phase Angle Modulation, Pulse Width Modulation (PWM), Frequency Modulation, and Bit Angle Modulation. I will need to investigate these methods of LED control, but I am currently leaning toward PWM or BAM.
