hello,
I am in the process of designing a scoreboard for a competition at my school. I am intrested in using 7 different·LED digit displays but i cannot figure out how to control all of them with one stamp. Is there any way to do it without networking multiple BS2's together?
Thanks

    Obviously you don't have enough outputs on the Stamp, so you need to expand. If I were doing this project I would string seven 74HC595 shift-registers together; one shift register for each scoreboard digit. StampWorks shows how to daisy-chain the '595.
