Hi guys,
probably there are already other topics about this problem, but I haven't my ideas so clear, so please forgive me. :~
I have bought the 7-segments and 4 digits display ( https://www.sparkfun.com/datasheets/Components/LED/7-Segment/YSD-439AB4B-35.pdf ) and i want to try to pilot it through my Arduino.
Could you please explain to me how to connect the pins to my Arduino board?
Many thanks!
it is on the sparkfun side ...
First of all, thank you for you answer!!
Anyway, I still don't understand how to connect the Arduino with the display! 
Could you please tell me which is the mapping between the Arduino pins and display's ones?
Thank you
Hi, I have the same 4 digit Seven Segment Display (bought from another supplier - not Sparkfun, but its the same module). The vendor where I bought it mentioned on his website that the pinouts are wrong in the datasheet you mentioned (got the same datasheet as well - but its wrong).
Note: The pinout in the datasheet is incorrect. This is the correct pin-out:
1: Digit 1 16: B
2: Digit 2 15: G
3: D 14: A
4: Colon Anode 13: C
5: E 12: Colon Cathode
6: Digit 3 11: F
7: Decimal Point 10:Apostrophe Anode
8: Digit 4 9: Apostrophe Cathode
Just tested with the Pinouts above sucessfully.
Hope it helps
