7 Segment Led Board

The_Apprentice

Hello Everyone,

I'm loocking for some information about how to make a 7 Segments Led Board using regular led's, I pretending to drive each line with 10 5mm Led's
something like this:

... O O O O
O .............. O
... O O O O
Just don't pay attention on the dot's, I coudn't make my grafic better.
I attach a Better grafic file.

Please if somebody have some ideas in how to do this board , please let me know, I'm rushing with this project and my time is to short.

Thanks.

It's really a matter of connecting a bunch of parallel LED circuits -- then putting a driver between them and the BASIC Stamp. You could use something like a ULN2803 depending on how much current each LED group requires.
