Breadboard
| A breadboard is used to easily connect components together. It contains many holes for the connections to be made. | 
| |
| There are four different sections of holes on the breadboard. Holes in the different sections are connected in a different way. | 
| |
| Holes in Section 1 are connected together horizontally. All the holes in the red row are connected together and all the holes in the blue row are connected together, but the holes in the red row are NOT connected to the blue row.
The convention is that the red holes are for 5V (positive) and the blue holes are for GND (negative). Similarly, holes in Section 4 are connected together horizontally. Again, all the holes in the red row are connected together and all the holes in the blue row are connected together, but the holes in the red row are NOT connected to the blue row. |

Holes in Section 2 are connected together vertically. Holes in Section 3 are connected together vertically. But the holes in Section 2 are NOT connected to the holes in section 3. |

| Here is a typical picture of how connections are made on a breadboard. | 
| |
| This is an example of making correct connections. |

| This is an example of making wrong connections. |
