3.4.2 Hello, Breadboard!
To use extended electronic components, a solderless breadboard will be the most powerful partner for novice users.
The breadboard is a rectangular plastic plate with a bunch of small holes in it. These holes allow us to easily insert elec-
tronic components and build electronic circuits. The breadboard does not permanently fix the electronic components,
which makes it easy for us to repair the circuit and start over when we make a mistake.
Note: We can use the breadboard without using special tools. But many electronic components are very small. A pair
of tweezers can help us pick up small parts better.
There are many detailed breadboard knowledge on the Internet, let us use it wisely.

• What is a BREADBOARD? - Makezine
For breadboards, what you need to know clearly is:
1. Each group of half rows inside the breadboard (such as column A-E in row 1 or column F-J in row 3) is
connected. This means that when an electrical signal flows in from A1, it can flow from B1, C1, D1, E1, but not
from F1 or A2.
2. Both sides of the breadboard are usually used as power buses, and the holes in each column (about 50 holes) are
connected. Generally speaking, the hole near the red wire is used to connect the positive power supply, and the
hole near the blue wire is used to connect the negative power supply.
3. When building a circuit, the current flows from the positive pole and must first flow through the consumer before
it can flow into the negative pole. Otherwise, a short circuit may occur.
Now we should have a general impression of the breadboard circuit, why not try to build a “Hello, LED!” expansion
circuit?
