Thank you for your quick response!
Did you test your equipment before soldering it together? Then after soldering it does not work?
Unfortunately I did not, but the arduino and the power supply were already in use as an ambilight some months ago (I bought a preassembled kit back then). I got a new screen, so i stored the devices until yesterday, when my new LED strips arrived. Everything worked until then.
Is it three wires you are connecting: 5V power, +data (PD5), then ground connection on the strip?
Exactly. Also for good measure I also connected ground from the arduino with the ground pin from the strip. Is that a problem? It used to be wired that way before… but the old strips had less LEDs.
By this you mean that no V is seen or it is acting like it is not connected, it is binary so it has the neccasary V or it does not (0V or 5V).
I updated the fastled library on the arduino und set it to use port5 of the arduino. When everything is connected I turn on prismatik and it says it sends signals to the arduino. The work indicating led on the arduino blinks accordingly. But the led strip blink does not change. Unfortunately I have no device to measure if there is any output from the pad.
You need to make sure you did not fry the arduino. Is there a way to check it by software? But it behaves as it used to, when the old ambilight was working.
Quick search I found this short video with great information:
Thank you for the recommendations! I‘ll check them out!
