I would like to build a square wave generator:
50% duty cycle
0v to 5v peak to peak
adjustable frequency from 50Hz to 300Hz by controlling an input voltage from about 0vdc to 5vdc.
The tricky part for me is making the frequency adjustable. The input voltage won't generally go below .05vdc or above 4.95vdc for this control. .05v will ideally generate 50Hz, and 4.95v generate 300Hz, but want to learn enough to be able to tune this as the control voltage may not be perfect in the field.
Edit: I've built a generator using a 555 timer before using a schematic on this forum.
Thanks!
