Frequency meter

This circuit changes the output  proportionaly  in responds to the change in input frequency. If you adjust the input period (sweep time) to 1ms the output will change the frequency of the output. Adjust the  input period (sweep time) to 10 ms and the output frequency  changes to as well. I found for this arrangement the circuit works best with input periods from 1ms to 10ms. If this  meter was analog it would increase and decrease linearly as the  input frequency changes. The potentiometer is used to calibrate the meter for a linear style meter.
