RGB LED controller not functioning correctly

by jordanklaers on Wed Sep 11, 2019 3:12 pm

I purchased the RGB LED controller
https://www.adafruit.com/product/1005

And it does not produce the expected color outputs.
I have tested the terminals with a multimeter to verify the correct power levels per color. Such as power on the red channel and no power on the other two after touching red, but there seem to be done very apperent issues.
I Have included a video as well as some photos of me using the multimeter one the channels with different colors applied.

Which LED strip are you using? Can you link to product page.

I am using the strip recommended from the page that I purchased the controller from

Thanks. Those should be fine.

It looks like it's working as expected in terms of the color channels from your photos. It's red when there's power on the red channel, etc. From the video, it looks like it's behaving erratically to the touch inputs on the wheel. Sometimes it works. Sometimes it does nothing. Sometimes it sort of jumps around randomly. Is that generally correct?

What are you using for power?

Can you post some more photos that better show the wiring connections between the LED strip and the controller.

I am using the power source recommended on the same page, you can also see it in the screen shot in my previous reply. Which contains all the material purchased for this.

In the Google drive for the two red pictures I was attempting to show how the red channel does have power but the other channel also has power which shouldn't be occuring for a solid red color (unless I'm missing something)

Attempted to show the same issue between the two images with the strip at blue.

I have included more pictures of the wiring in the Google drive for you to check out

Thanks. It might be a connection issue here. These look like maybe they are a little cold soldered. Can you post another photo of this solder job more in focus:
