Hey,
I just ordered a bunch of those bargraphs:
but now I’m wondering, how to connect them to the DOUT, because some LEDs are using the same pin for supply and ground, if I get it right…
Thanks,
Chris

Independent control of the LEDs isn’t possible with such a wiring.
And even for a meter like display, they would require a special control software.
Unfortunately multiplexing (like for LED rings) isn’t possible
-> sell them on ebay, and search for a better suitable hardware.
Best Regards, Thorsten.
Hey TK,
yes, I already realized that by myself. I now wanna use single square-LEDs which I connect in a matrix.
I will get the CCs from bidule. That works on my iPad perfect.
