Connect 12-segment bargraph to DOUT

[FantomXR]

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.
