    Should I buy a breadboard with a 5 volt regulated power supply or get
    a regular breadboard without one?

    Thank you.

    As a general rule, the breadboard + power supply kits don't save you
    that much and are a lot less flexible than separates. In addition, you
    may want something other than +5 if you ever use op amps or lower
    voltage stuff. Something like this would do you for
    a while. It's not Lambda Power but still...

    It would help, though, if you could mention some specifics about what
    equipment you have in mind.

  3. Whatever you do, you will need a power supply of some sort - having it
    built into the breadboard may be convenient.

    If you expect to work with microcontrollers or other digital logic,
    you will probably want a 5 volt supply (although many parts these days
    are designed to work on lower voltages.)

    If you will be working in the analog world (audio amplifiers, for
    example) you will want bipolar supplies +/- 12 - 15 volts, typically.

    "stuff" (cause I don't know) with Microcontrollers and Microprocessors.

    Just get one without built-in supply, then you can experiment whatever you
    are building *even* on stability with respect to power supply
    Also, depending on what you are trying, more as one supply is needed so put
    money in a decent dual output supply of say 6...10A 0..30V

    I'd get one without (it's more flexible) and use some of the money saved
    to buy a few 7805's. Personally, I mostly use a 9v battery with a 7805
    and capacitor soldered directly to the battery clip - effectively a
    regulated 5v battery :)

    So I don't have to have one plugged into the wall?

    Well, obviously, _something_ has to be plugged into the wall, unless
    you're just using batteries. But that doesn't have to be the breadboard.
    I have a "bare" breadboard like that, and I have a couple of power
    supplies lying around that I use when I need them. All home-built,
    of course. :)

    Have Fun!
