  1. thanks for the reply, mike. i have to say that i am very, very new at all of this and i think i get what you are saying, but lets see. i think the schematic you put up is in series. when you flip one switch it uses the value of just the one resistor but if you flip two or more, then you would use the equation to figure out the value? i'm sorry because i know this is all probably all very easy but i just can't seem to get my head around it. thanks again brian
  2. hello. i am still very new to any kind of electronic projects. i am to the point where i can read simple schematics and put them together and have them work on the first couple of tries but i am trying to do something here kind of of the cuff. i found this schematic for a photo theremin (which i was later told is not any kind of theremin but some kind of transistor, but any way). i have built one now and got it to work and know i want to take the photo resistor out and put other things in to controle the pitch. what i am planning on know is a series of swithches connected to resistors to controle the pitch, puch one and its this sound, push another and its this pitch, basicly trying to make one of those cheap keyboards i used to get when i was a kid that had candy in one compartment. i originaly thought, for some reason, that i could take two resistors and hook them together and it would combine there resistance, then i put it on a breadboard and it dawned on me that it is only going to be the resistence of the lowest resistor (i think).
