hello people,
I am trying to make a score board with 18 Seven Segments. I am planning to use a PIC microcontroller.
But I have no idea how I am gonna connect all Segments and switches to one or two PICs.
I would really appreciate if anyone of you likes to share how to connect them.
thank you very much indeed

u need 26 output lines to connnect 18, 7-segments. i think it can be done with single 40 pin micro

You can use the Multiplexing Technique for reducing the i/o pins......

but multiplexing technique will unnessary increase the the complexity in that case... simply by using transistors and few i/o pin coding that thing can be done very easily....

you can do this using Multiplexing techniique.
Go to proteus
type
7-seg-mpx8-cc-blue
pic
and use it according to ur requirement
