Sound Signal Generator

So this is a sound signal generator, it is capable of generating sounds with frequencies from 100hz all the way to 3000hz. There are 2 modes on the sound generator, the first mode(Mode1) plays a scale from 100hz to 3000hz continuously going up by 100hz each interval that is 1sec. The second mode is a mode where you can change the frequency to whatever frequency you want by turning the knob on a potentiometer. Another thing about this signal generator is that you can always see the frequency of the sound the generator plays at all times on the LCD display, no matter you are in mode 1 or mode 2.”
