Here's a cheap and easy way to check and measure wave forms coming from your·Basic Stamp projects.
See Post below for realtime software. You can time your code's instructions and loops by setting a pin high then low and measuring it in cool edit with the selection tool.
It's primarily designed to work with 5V but you can use resistors to divide higher voltages. The Optocouple protects your computer.

My question:
An internet address was given along with a schematic that has optotransistors, which can be used to feed inputs to the downloadable·'computer oscilloscope'.·Are there other circuits, such as voltage dividers, that could be·used?
Thanks

circuits, however, optoisolation is still needed to protect
the computer in the event of a short or component overload.
Some computers have a sound card input while many
portable computers have only the headset input jack. The
ratings between the two are significantly different and
should also be a consideration.
