#83177 Hello to everyone,
i bought this seven segment display:

https://www.amazon.it/HiLetgo%C2%AE-dig ... way&sr=8-2, but it's not working at all.

I'm following this tutorial:

https://www.google.com/url?sa=t&rct=j&q ... HPaIaorwCQ

and i downloaded this libary : http://playground.arduino.cc/Main/TM1637.

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.
