Re: Re: [Development] Lights, using two micros.

I defo think we should do the lighting module BEFORE the LCD that will
control it.  Is the lighting pack is built it can be operated from a PC but
if the LCD is built first there will be no switch to control with it.

I know little or nothing about PICs but if they're cheaper and can do the
job then use them.
