All very good ideas!! But he is a beginner I think. I like the bargraph idea allthough it is a bit crude I think. But it is the simplest idea I heard yet. No code no expense and simple to do.

The other idea of using an interface card and Visual Basic seems over the top. Plus didn't he say he wanted it outside also? A computer may be out of the question. If you were going to use a computer I would think the serial/parallel port would be simpler and cheaper.

simpliest way would be a program to make Numlock / Scroll lock / Caps Lock flash on/off KLocks (6KB)

Batch file to continuously flash all Lock indicator lights:-

    @echo off
    :: Turn all lights on
    klocks +n +c +s
    :top
    ping 127.0.0.1 -n 2 >nul
    :: Toggle all lights
    klocks !n !c !s
    goto :top
