. and i really dont know whats a butterworth lowpass filter.guys i just need a simple idea!!.like christmas lights or a LED counter that counts from 0-9 by using capacitors or whatsoever.the main focus is on energy storage elements that are capacitors and inductors.so a project idea should be the one that includes these..RLC circuits i mean offocurse!!..but i just cant present a RLC circuit on a breadboard .i should relate it to some daily applications.i hope i made it clear .please think up.thanks
