Psykhaze Posted April 22, 2016 Report Share Posted April 22, 2016 Hi there ! A simple question with maybe a complicated answer: - Is there a simple way to drive rgb LEDs , to make a multicolor BLM ? From what i understood DOUT module only provides ON/OFF outputs and AOUT module seems to be more designed to drive old analogic synths than LED. Thanks in advance for your answers , this subject may have already been covered but i did not found the answer simply. regards, JK Quote Link to comment Share on other sites More sharing options...
latigid on Posted April 22, 2016 Report Share Posted April 22, 2016 DOUT can also provide a type of PWM, but it only works well when the LEDs are addressed individually (i.e. not in a matrix). Which means quite a lot of DOUT pins. A better method is to use WS2812 LEDs which respond to a serial data chain. See the end of that thread for working layouts with 4*4 Sparkfun button pads and illuminated encoders. Quote Link to comment Share on other sites More sharing options...
