Throughout this class, we will be using a 'breadboard' to prototype our circuit build - and to make modifications to it. But in order to be successful, you need to know how a breadboard works.
A breadboard is basically a 'pre-wired' system that follows some basic rules:
- Each of the 5-hole columns are electrically connected.
- The channel in the center of the breadboard prevents a connection across columns.
- There are power 'rails' along the top and bottom which are connected.
- I've pre-wired the breadboards to connect the top and bottom power rails.
We create circuits by placing electrical components on the breadboard and using jumper cables (and the pre-wired connections) to tie components together. We will go through the process one step at a time.
