This article is a simple principle of variable frequency oscillator commentary. The principle is simple but effective. For your grasp this principle more effectively, please read this text combines schematic. This is a very simple circuit using the 555 timer IC generates a square wave frequency, you can adjust a potentiometer. And values ??for a given frequency can be adjusted from a few hertz to a few kilohertz. To obtain very low frequencies instead of 0.01 uf  capacitor  has a higher value. A good choice, R1 and R2 in the megaohms kilohms. Then you can choose C repair frequency range. If you are reading this first principle, the proposed Duokanjibian, grasp this principle.
