Well we eventually burnt around 1m of leds in course of 5 months, trying to fix the circuit and program. First and last led controllers stopped working.
There is an video, showing the project in the first post. We wanted to do cealing lightning with leds, that are stuck between the wooden piece. Theres not much to show of the controlling box. There is just an AC wire going into Power supply and the rest is shown in the sketch.
1k = 1000uf 16v Electrolytic Capacitor
GND input in DC-DC is connected to GND output.
GND of the Leds werent connected to controller ground because we didnt think it was necessary, and thought that its automatically grounded, because its one circuit.
Yes, we use the converter with UNO aswell and it works perfectly fine.
We tried FastLED example program with UNO and Wemos. Uno worked perfectly, but Wemos didnt give a sign. It seemed working, but leds didnt show anything. We tried diffrent pins for wemos aswell, but maybe data is too weak?
Picture file was too big for the site:
Thanks
