Hey all.
OK, I am band new, both to electronics and to the forums.
So, I put a question to you all.
I did a search on the word "trimmer" and got a few hits.
But it didn't quite clear up my confusion.
I am attempting to build this.
however, the person did not go into a detailed "howto", and as I said I am pretty much a n00b.
Now, the actual question:
In there he uses a variable resistor/pot/trimmer.
I managed to sourse a trimmer, but I don't quite understand how it works.
It's got 3 pins at the bottom.
From the previous search I did, it seems like you only need to wire up 2 of them to use it
as a variable resistor (Increasin or decreasing the current that passes through it).
Can anyone explain to me in layman's terms how to wire this up?
I am guessing there's a + and - side on the trimmer, and that it is simply wired in serial.
Am I guessing right?
