I'm a vb programmer. I need to read a basic on/off switch and wanted recomendations on the best way to do this. It sounds like the parallel port may be an easy/innexpensive way. I also want the ability to read many of these from one computer. For instance I might need to read up to 60 at a time. That tells me serial because it's expandable. I've also hear about digital input but it sounds like I don't need that. So my rec is:
Need ability to expand to read many switches Innexpensive Easy (since I'm an electronic newbie)
Any recomendations appreciated.
