Variable frequency square wave generator based on IC 555 calculatorSquare wave generator based on IC 555 online calculator allows you to easily determine pulse frequency and other parameters of a circuit. A square pulse generator built on the basis of the popular 555 microcircuit works as a multivibrator i.e. in self-oscillating (astable) mode. This is a mode in which impulses arise themselves, without any external influences. Adding a variable resistor R3 to the circuit allows to get variable pulse frequency. To calculate the min (f1) and max (f2) pulse frequencies, you can use the following equations:
f1 = 1 / (0.693 * C1 * (R1 + 2 * (R2 + R3))), where:
f1 min vibration frequency As follows from the calculation, in such a generator circuit it is impossible to obtain an exact filling of 50%, that is, a clear meander.
