Very simple question, I know, but I can't find the answer:
I bought a 4 digit 7 segment LED Part Number LTC-4727JS made by LiteOn. It's the first time I am trying to use one of these.
The datasheet at
http://optodatabook.liteon.com/DataBookFiles/12826/C4727JS.pdf
doesn't seem to say (or I can't understand) whether each segment needs a resistor to limit current. I want to know this before I connect it so I don't blow it up the first time. Can anybody tell me whether each segment needs a resistor, and if so, what size? And if I could figure this out myself from the datasheet, how should I have done that? If it DOES need a resistor, what's the best way to handle the 28 resistors that would apparently be needed?
Thanks in advance for any suggestions or comments.
