Breadboard help

  1. Mar 17, 2014 #1
    1. The problem statement, all variables and given/known data

    Basically construct the circuit on a breadboard and take some measurements:

    2. Relevant equations

    3. The attempt at a solution

    My only question is how am I supposed to do the GND grounding that it wants? o_O

    What kind of breadboard are you using? Many breadboards have bus strips that run their length, to let you more conveniently connect power and ground in many parts of the breadboard. Can you post a picture of your breadboard?

    There should be a spot designated for the ground wire on the bread board.

    Here's the breadboard...

    Do you have the connection diagram for that breadboard? It has a very specific way that the plug holes are connected internally.

    This tutorial about breadboarding shows how the holes are connected on a typical breadboard:

    The only difference with your breadboard is that there are 2 halves to the breadboard. The long power bus strips are separated in the middle (note the slightly wider gap there), so you need to jumper between the halves if you want to carry a voltage or ground down the full length of the breadboard. Use a DVM and a couple wires to beep out your breadboard to be sure you understand how to hook things up.
