I have the desire to add a frequency display for a clock generator. Certainly not necessary, I can use my DNN, but it would be nice, I found a veritable plug & play frequency counter and LDC display for in excess of $50 USD at Digikey. I didn't have to pay a tenth of that for the clock generator.
I have 1 $20, el cheapo, backup DMM for when I need to measure more than one thing at a time. It has a frequency counter/display. Therefore I would think there must be a way to get this functionality at a reasonable price.
I'm sure I'm over-thinking this and a simple solution is avoiding me. Any ideas on how I can count the number of clock pulses per second and display the results, (7 segment LED would be preferred)?
