this project has defeated me. i give up. i am able to kinda see a randbow when i reboot the pi but not like in the picture. once it boots up, the leds are not being able to control via the app or the software yet i have the pins connected correctly and am using the pre-soldered cables that came with the led strip so i have not touch that. i have tried with openelec latest version on a pi3 and also on a pi1 model b using raspbian.
