1  Using Arduino / Displays / 4 digit seven-segment display ! on: January 18, 2013, 07:26:10 pm
Hello, I am new to arduino, just got it a few days ago smiley

So I have this 1 digit 7-segment display, I got it to work, displaying numbers and letters..

Now I want to use the 4 digit display, but it has 12 pins, and everything I find online is either 16 pins or 10 pins...

The following picture is a picture I took just now...


So I have 12 pins ...
I wish to know what pins to connect to the digital outputs, and what I connect to ground...
(Also, do I need 5v? Did not need for the 1 digit display.)

Thanks in advance, Hilmar. smiley
