Computer chips—integrated circuits that process information—are made with pure silicon crystal.

LEARNING WITH ARDUINO

Arduino is an open-source microcontroller board—a simple computer—that runs a simple program over and over again. Makers write code in Arduino’s software, which tells the microcontroller what to do. Arduino is powered by batteries (regular or solar) or electricity from an electrical wall socket. Arduino is easy to build and modify, allowing you to make all sorts of interactive toys, tools, gadgets, and robots. You can even program Arduino to send a Tweet when your morning coffee is ready.

To make a basic Arduino, you’ll need an oscilloscope to monitor voltage and the continuity of an electrical circuit. You’ll also need a soldering iron to attach components and wires to a circuit board. Additional tools include wire cutters and wire strippers. Eventually you’ll learn how to design your own circuit boards. This will enable you to create more advanced projects, such as robots and mobile devices. More complex electronics include robotics, which calls for more advanced tools and problem-solving skills.

Arduino Uno is the most common type of microcontroller motherboard. Mega’s slightly larger circuit board follows Arduino Uno in popularity. It comes with a 256 KB of memory, eight times more than that of Arduino Uno. Arduino Mega ADK is a specialized version of Arduino Mega. It interfaces with Android devices. Arduino LilyPad uses conductive thread and is specifically designed for textile projects.

ADVANCING TO RASPBERRY PI

If you plan to build a more complicated project or one that performs more than a single task, you’ll need Raspberry Pi. Raspberry Pi is a general-purpose computer that uses a Linux operating system. It’s a bit more complicated than Arduino, but just as fun, and even more functional. Examples of Raspberry Pi projects include an automated cat feeder and a tea kettle activator that measures water temperatures before lowering the tea into the kettle for brewing.
