i thank anyone who can give me tips on this
ok. in the first picture, the audio xformer (in the circle marked 'A') i have the device. it's a radioshack #273-1380 audio xformer. it has four wires.. i can figure out the names for them via a datasheet, no problem. but that symbol in the schematic looks weird, how do i hook it up?
next, is B. it looks like a simple power circuit.. but why do i need to wire it to ground between the batteries.. and isn't the batteries already ground and voltage? so.. i would just be wiring that one battery to itself.. which is dangerous.
C. U1a and U1b are IC chips. i don't know what that symbol means though. does the plus and minus refer to certain pins? the only thing i'm certain is that the tip of the triangle must correspond to the 'output' pin. if you need a datasheet, the IC is a 'dual op amp' radioshack # 276-1715
D. again, this is an xformer.. radioshack #273-1380 although this time, it looks like this xformer only has two wires. the other one had 4. mind you, i haven't bought this yet.. the only picture i have is on the radioshack website there.
and where the big X is, i'm using an arduino circuit instead of that very costly precision waveform generator chip.the second picture is just so if you can't see clearly under my writing in the first.onto the third picturei have two questions here...1. the part of the circuit labled 'AMP' it looks like a potenimeter? but both amp chips i have are chips. so, what does that mean?
2. while i know what a normal capasitor looks like, i don't know what i'm supposed to do here. instead of just the two lines going paralell, one is a semicircle.. and the other is straight.. then there is a + sign above it. what does that mean? is there a difference between the normal capasitor symbol and this one?
what is ground then?
"Amp" stands for "amplitude", not "amplification", I believe.
