Can you help me identify these components?

    The truth is I am a really noob at this, but I really want to be able to do my project. First step of course is identifying the components. I know the basic things, like this is a resistance and that is a transistor, but I dont really know what the other things are.
    Like in this picture, whats the white thing that keeps all the components together called? Or here, , whats LDR, or P2?
    Please help a fellow noob. If you could give me a list of all components, that will help a lot. Also, the both images are for the same circuit. Thanks a lot!

    The circuit board is called "Veroboard",, or Breadboard,

    if you cant read the circuit diagram to identify the components, how will you be able to make it!!

    Thank you. This is something to start from. :)

    It looks like some sort of amplifier circuit. Anyway, google 'op amp 741' and you'll get a picture in images like this:

    Hmm, I just saw your other picture and that is 741J in a DIP ic circuit. yeah, that's that part above - cool...

    The two P's are the potentiometers that look like they're at the bottom of the picture (the black circular parts).
    There's another potentiometer which is the 100k part and that's the large silver one on the top of the circuit board.

    BTW, I'm a relative newbie as well, so be careful w/ my suggestions here, but I'd go w/ those answers on jeopardy...

    I was just informed that digikey is not the 'lowest' cost parts supplier and I always have a hard time finding stuff at their site anyway. You might try Jameco or if you live in NorCal you can try a Fry's for that breadboard and some of the components. Looks like kit.

    For the breadboard I googled solderable breadboard and found a couple looking like the picture. Depending on what you want to do w/ that you might go w/ a solderless breadboard so you can use it again (more easily). I was working w/ an electronics pro and he probably uses both, solderless for sure.

    Good luck. I'm struggling as well trying to figure out how some of other components work, not always that easy, but keep at it.
