Do you believe with a measly of $7, and you will get a 16F84 PIC frequency counter?

Well, in fact a counter would only cost you less than $2, while the LCD display will cost you a little bit more, which about $5 each.

Those simple and user friendly features in the 16F84 PIC frequency counter also elaborated the uniqueness of it as well.

There are several sophisticated characteristics in this frequency counter, and you might be having the interest on this project even more. Those features are:

A very cute stand alone frequency counter.

A comprehensive digital readout function, which you can eventually set the IF
offset to any of three combinations i.e.: VFO+IF…. VFO-IF or  IF-VFO with the mode switch.

Turn the frequency counter into a Gig region; with just a simple modification, (The additions will include the pre-scaler).

A typical 14 MHz count will be around this figure: 14.060.45.

Note: Make sure you can mount the frequency counter into a 2N2/20.

It is always a fun experience to build a simple and reasonably cheap frequency counter.
