Libreelec and ambilight

  • Hi guys hope you can help so i bought a few things to try and make a ambilight for my system. Im running libreelec of a mini itx computer and would like to now a bit more i found a few articles but it looks like it gos more into the raspberry pi version.

    So i have a few questions

    A thread mentions that i need to have the following

    1. AVR Receiver
    2. HDMI to Analog converter
    3. 2 port HDMI splitter
    4. USB Video Grabber (Easycap)
    5. Composite cabel
    6. Active USB Hub

    is this all needed on a build where you running mini itx? wouldnt you just use a hdmi splitter and then go into the rasberry pi?

    I bought the following

    1. Arduino Uno R3 development board OEM
    2. WS2812B RGB LED STRIP 60/M 5VDC IP65 I need 4 meter
    3. Raspberry Pi Power Supply 5V 2.5A (Pi B+/2/3) with Switch
    4. Raspberry Pi 3 Model B+
