What to do to make this work??????????
I've decided to take a look back at your previous posts.
Pavle, you have on multiple occasions asked very vague questions and ignored direct questions.
I would strongly encourage you to slow down and try to be more observant.
The picture you uploaded shows multiple faults:
-It's very messy.
-It's looks like it was intended to be connected between left/right channel instead of using the ground lead.
-It looks like it's shorted.
-It's quite possible to damaged the LEDs or jack with excessive heat.
Please revisit some of the basics of electronics so that you understand the basics of series and parallel circuits. Additionally, buy/borrow a multi-meter because they are very important in troubleshooting.
If you have a meter, please use it on the device you had made and report back to us.
In the mean-time, I am un-following this thread, so I will not see when a replay is posted.
