    Well, you can't do much with just a counter by itself. At the very least, you will need a supply of power, something to provide it with a clock so that the counter will advance, and a way to determine what the current count is.

    Why don't you start by downloading a datasheet for it, so that you will have an understanding of how it is supposed to work?

    You can download a datasheet here:

    Note that this datasheet describes four distinctly different counters, in many different package configurations. Unfortunately, this isn't an easy datasheet for a N00b to decipher.

    Google "74LS161" to get the spec sheet. You might find that oniy one won't let you do too many projects.

    Please don't use all caps. It's like you're yelling for attention.
