Hi guys and gals,

Any suggestion on a simple data acq, say 8-port, to receive 0V - 5V from a manual switch, that can also interface with RS232 or USB? Is it possible to make without using mcu?

Thanks! ;-)
 

Of course it can be done without a small mcu but it would be like going back in time by, say, 20 years ..

Now, have a look at PICAXE18, picture is attached, and see if you can find anything simpler than that ..
