I have found this tutorial but don't have a 0.1uF Capacitor. I am an amateur when it comes to electronics, but I don't know if I can swap 0.1uF for a 1uf or 1.5uf. Any help would be greatly appreciated.
A film capacitor has a much higher self resonant frequency (SRF) and hence a lower shunt impedance to suppress impulse noise. You must not substitute an electrolytic cap otherwise it will not perform the same for noise ripple suppression.
Ceramic with high SRF may be used for low voltage and metal film must be used for high voltage such as in IGBT snubbers.
All caps have this property but if the datasheet does not specify the SRF , which varies widely depending on source and family , you can assume it is not a special high SRF component.
C3 should be a low resistance type: ceramic or metalized film. and yeah using a larger capacitance will not be a problem.
