In our case, to determine the value of an unknown capacitor, we could build a circuit with an unknown capacitor in series with a known resistor and a power source. Using an oscilloscope, we can measure how long it takes to charge the capacitor to 63.2% of the initial voltage.
Now power up the circuit using the PWM signal and observe for a resonance signal on the scope. You can try changing the value of capacitor if you do not get a clear resonance frequency signal, commonly 0.1uF capacitor should work for most inductors but you can also try with lower values like 0.01uF.
As you can see in the screenshot below, we can also use the discharge (falling edge) to determine the value of a capacitor. If you don't have an LCR meter handy, a function generator and an oscilloscope can be helpful to measure a capacitor value. You can expect a capacitance value of 3%-5% uncertainty.
