Setting Up Hyperbian – Ambient Lighting with your Screen

Hi @Tim

Need your assistance here.

I have tried to follow your instructions, the only difference is, I use the following:

The rest are using the same materials you have:

I have an issue where the LED strip does not lit up at all. I have a feeling that I might have a dud LED strip; but would you be able to confirm my connections?

What I have done so far:

  1. Confirmed the power adapter is 5V (it’s around 5.10 when I tested it with multimeter)

  2. Stripped and Connected the LED strip red (+) and white (-) cables TO the DC barrel Jack Adapter

  3. Connected the LED white (ground) cable TO the Raspberry pi Ground port using jumper wires

  4. Connected the LED green (data) cable TO the Raspberry pi GPIO18 port using jumper wires
    Notice, I didn’t connect the LED red (+) cable TO the Rapsberry Pi; as my power adapter is more than 4 Amps (following your video instructions)

  5. Connected the HDMI capture
    Source > HDMI USB Capture > USB input of Raspberry Pi && HDMI out to the monitor (refer to the summary pic below)

  6. Powered up the Raspberry Pi (through a normal micro USB input)

  7. Powered up the HDMI USB capture card (through a normal micro USB cable)

I can detect the HDMI USB video capture and see the live feed video in the hyperbian app, but I cannot see the LED strip to lit up at all

I have tried the following too:

  • Tried to measured the voltage from the other end of the LED strip cables, and it stated the same (+/- 5.1voltage) - which indicated the power and connectivity is there
  • Tried to increase the image process brightness to 50% in hyperbian
  • Only connects the power adapter to the LED Strip (removed the Raspberry pi connections)

I noticed there is an arrow on the LED strip, I suspect I need to connect the power from the source?
E.g. Power Adapter >>> LED STRIP
and not the other way around, something like this: Power Adapter <<< LED Strip

1 = Power input for HDMI USB Video capture (micro USB)
2 = HDMI Source (from computer)
3 = HDMI output (to monitor)
4 = USB output to Raspberry Pi (to 8)
5 = Power input 5V 6A for LED strip
6 = Data (green) and Ground (white) connectors to Raspberry Pi 3B+
7 = Power input for Raspberry Pi (Micro USB)
8 = USB input from HDMI USB Video capture (from 4)

Thanks heaps!
