Need help with led

[alrevuelta]

If I understood correctly, you would like to change the colour intensity of the RGB leds? If so, please have a look to this example. The intensity is a value from 0 to 255, so if you set 100, it will be less brighter. First element in the array is R, second G and third B.

void setup() {
  // Configure the colors when the LED is not pressed
  uint8_t offColors[3] = {255, 0, 0};
  mdm.setOffColors( offColors );

  // Configure the colors when the LED is pressed
  uint8_t onColors[3] = {0, 255, 0};
  mdm.setOnColors( onColors );
}

Is that possible to adding more color than 3 color basic?
I just test with this library but the led not bright with button push

Regarding your first question "Is that possible to adding more color than 3 color basic?" Yes, it is possible, you can do something like {100, 25, 200} and you will be mixing some red with a bit of green and a lot of blue.

If you load the code that I mentioned above, you should be able to see the colours that you have configured. I assume that you have a MIDI receiver open in the computer. Let me know if it doesn't work for you, but please, state your problem with providing more details.

I need the schematic before made the pcb of this example:

, can you define the pinout to me of cd4067 and matrix, led, I use the diy 4x4 button matrix pad and 4x4 ws2812b, thank you!

All the documentation can be found in this repo. For pinout refer either to the Wiki or the pcb schematics here

Since your initial question was already answered, I'm closing this.
