As we know that in electronics we have various types of waveforms such as square wave, sinusoidal wave, and triangular wave.
We can easily generate these waveforms by using a function generator system but it costs very much.
So here is the cheapest square wave generator circuit diagram through which you can generate square waves easily.
What is a Square Wave?
A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between the fixed minimum and maximum values, with the same duration at minimum and maximum.
Square waves are a very useful waveform that we used in many projects. We also have square wave inverters that worked on square wave
You can easily generate square waves using an op-amp IC and few more electronic components.
1) 741 op-amp ic
2) 47k, 100k, 2x 10k Resistance
3) 2.5M Potentiometer
4) 10nf capacitor
