Project help

Hello everyone,

I have a little project that I need some help with. I have seven switches and seven LED's, switch one would light LED 1, switch 2 = LED 2 and so on. This I can do, but I want to have the LED's about 3 feet away from the switches and in a small place. I don't have enough room to get all the wires in that are needed. I can get about 3 or 4 wires through the space. So my thought was to use a chip (PIC I guess) to encode the switch value and send this value down a 'data' wire to another chip that will decode the value and switch on the relevant LED. I have attached a drawing of what I would like to make, hope this helps explain what I want to do.

The bit I need help with is how to encode and decode this signal. Would I need to do this with a PIC chip or is there something I can get off the shelf to do this?

Any advice would be much appreciated.

Regards,

Ian

This is a doddle... but then time is money and that means getting the books out . Get a book on digital electronics. ''Foundations of digital electronics'' (try fleabay) is ace and will tell you all you need to know... you only need 3 switches... read the baly book yourself you are along the right lines.
