Building a Circuit on a Breadboard Think about all the electronic devices you use every day--computers, cell phones, video games, digital music players (Figure 1). It's hard to imagine life without them, isn't it? If you're like most people, you don't know how these devices are made or how they work. Maybe you've seen the maze of electronic stuff inside a computer and thought: how could anyone make sense of all that? Well, the truth is that you don't have to be a genius to understand how electronic devices are made and how they work. Anyone can do it, and Machine Science's engaging hands-on projects will show you how. So, what exactly is all that stuff inside your computer? The simple answer is electronic circuits, which are arrangements of metal wires and electronic components (Figure 2). The wires carry electricity between the components, and the components do things such as store electricity and limit its flow. You don't need to understand all this yet. Just remember that electronic circuits are made up of electronic components connected by wires.
