#83177 Hello to everyone,
i bought this seven segment display: ... way&sr=8-2, but it's not working at all.

I'm following this tutorial: ... HPaIaorwCQ

and i downloaded this libary :

I followed the connection scheme from the tutorial (with the only difference that i'm using 3.3 V to power the display), but it is just always off.

Thank you for your help.
