Re: built in freq. counter

The only digital counters I see that Radio Shack carries are for "event" counting. These cannot be converted to a frequency counter. There are some "frequency counter" chips available that make building a frequency counter relatively painless, but I don't recall who makes them. There have also been frequency counter projects published in electronics magazines over the years.

Might want to visit the Poptronics forums at http://www.poptronics.com/forums, someone there might have a simple frequency counter. Off hand, a 1Hz clock that resets a cascaded decade counter, plus latches the counter word, would be a simple way to do it.
