7555 astable oscillator. make tones not war.
This 7555 astable circuit produces a wide range of frequencies without changing the duty cycle. In electronics labs at NYU, we used to connect the potentiometer wiper to pin 5 on the 7555, and the outer pins to voltage and ground, this did not produce as wide a range of frequencies, and the waveform would change duty cycle along with frequency. This made for difficulty measuring frequency response of passive filters.
