As you all know that there are different types of the waveform that you can easily generate by simply using a potentiometer and transistor.
But with the help of this circuit you can easily hear them as here we are connected speaker at the output of the circuit through which you can listen to the various frequencies when you rotate the potentiometer.
What is an oscillator?
An oscillator is an electronic circuit that generates repeated waveforms. One of the most commonly used oscillator circuits is made from a pair of transistors that are rigged up to alternately turn on and off.
And here in the circuit, we have to use the speaker to listen to the various output forms of the wave.
Here in the place of a speaker, you can also use a buzzer.
Components Needed;
1) 2x BC547 Transistor
2) 10k, 1k Resistance
3) 100k Potentiometer
4) 0.047uf Capacitor
5) Speaker
