I am working on a small project, and want to design a circuit that
will interface with a PC via a serial cable.
The circuit needs to pick up the state of a micro switch (on or off),
and then send the signal to a PC via Serial Cable, where a Visual
Basic program will pick up the COM state and react to the change in
state.
Can anyone suggest where to start.
Cheers,
Richard
