  1. sorry for bothering but I have many questions!
    I have a motherboard have 4 pin for RGB (+12v-R-G-B)
    I have a cpu cool which have 8x red leds 5mm
    I want to exchange them to RGB instead of red
    1- do I need 3x 470 ohm resistor for each led? or 3 are enough for all leds ?
    2- can I add RGB strip+ the previews 8 rgb Leds to this Circuit? (the rgb strip will include 6~8 leds only)
    I hope you reply me as soon as possible

  2. I watch your videos, and THIS is what I call Great content. Thank you very much. But the problem is that I don't have an Arduino and I would REALLY like to try this Project on Raspberry PI 4. Help is Appreciated.
