  • Im wondering if anyone knows how much resistance is needed? I’ve tried a bunch of resistors, but the values still climb.

  • Hmm. Do you know of any code (arduino?) that might be helpful?
    I probably should just hire a programmer.

  • Is it true that you need to upload new firmware on the new rgb led matrix backpacks in order to pwm the leds? or do they come with this capability?
    If you can pwm them.. How ?
    thanks.. Just want to adjust the brightness while spinning a potentiometer for now…

No public wish lists :(
