Driving RGB LED BLM

3 posts in this topic

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

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.
