ambient light application (DIY Ambilight)

by CH11LER

Hi everyone. I was wondering if anyone has any experience with this app. I've paid for it from the playstore and followed all the instructions on there website regarding the hardware side of things. I know the hardware works as the leds will flash Red Green Blue when they receive power.

When I plug the lights into my nvidia shield, it asks if I want to grant permission to the app to allow serial ports on usb which I grant. The app however, stays on "LED STRIP NOT CONNECTED" Out of frustration, I kept hitting the reset button on the esp8266 which is basically like unplugging and plugging it back in and I got a different message asking if I wanted to start video capture from the app which I allowed and for about 3 seconds it said "LED STRIP CONNECTED" But, before I could do anything the app crashed.

I have tried different usb cables too.

I've noticed the app hasn't been updated since 2020. Is it no longer fully compatible on Nvidia shield (2017) or something?

Has anyone got any experience with it?

Does anyone know of any other apps which can do this?

I really respect anyone who can help. I am not a novice with this kind of stuff but this has got me wanting to pull my hair out!

I used this exclusively for 3 years with no problems on my shield. I only recently switched to a Hyperion based setup because an exploit came out for my tv that allows it all to run on the tv now. Make sure you’ve flashed the aaa.ino package from their site (or FastLED) and that you’ve customized it according to your hardware setup selecting the right GPIO and baud rate. Most of the Chinese clones can only handle 115200 baud. Lastly, don’t count on the app to work once it’s failed. Reset your box if that happens then try again. If you’re still having trouble post your hardware and the sketch on your microcontroller

It should work out of the box, if you have a device like this:

but in general, i would recommend a separate HDMI Splitter + HDMI capture card -> Pi -> Led or Uno -> Led

Software capture is fine, but with capture card and with a HDMI switch, you can get amilight on other devices like a Console or something.

Something that worked for me was changing the serial baud rate (just keep trying the different values)

I read on this app's website that this value has to match the one in your light strip. So I guess that has something to with it not being detected. Hope this works for you!
