Ok, I'll explain what I want to do first.
This is the basic circuit I want to modify. **broken link removed**
But, what I want is to be able to control different patterns just like the above circuit, but control more led's that are further away.
I have been told that I could use a 74LS164 serial to parallel (shift register) ic connected to the serial part of the pic, I assume that I would use a pic16f877 as the serail part of these chips is much better?
I want 3 lines of 16 leds I want to be able to specify what line is tunred on and what leds to light up, and be able to light multiple leds, I do realise that if I turn 2 lines on and turn on an led it will light up on both lines, this is ok, but would prefer to be able to turn each one on but trying to keep wires down.
just wondering how do I connect the shift register IC to the pic how do I tell the pic which shift register to use (do they have address's? and if so how many can be used?)
Any help for this project would be great,
Thanks
