- We'll use the Linux operating system, via the Raspbian distribution, and leverage it to run our projects in Node.js.
- GPIO stands for General-Purpose Input/Output.
- Rick Waldron started the Johnny-Five project back in 2012 and wrote a program that used node-serialport to operate an Arduino Uno with Node.js.
- We run
uname -m
command on the command line of our Pi ssh session to find out what ARM architecture the Raspberry Pi uses. - Changing the default Raspberry Pi password is important because default username and password isn't very secure, especially when your Pi is connected to the internet.
- Node.js allows you to create even advanced robotics projects without having to deal with any low-level languages, also it has Event-based systems and Garbage collection/automatic memory management.
- Node.js prides itself on creating small, bordering on tiny, packages, and has the excellent npm package manager (and others) to help manage those packages.

Overview of this book
JavaScript has an effective set of frameworks and libraries that provide support for embedded device programming and the robotics ecosystem. You’ll be able to put your JavaScript knowledge to work with this practical robotics guide.
The book starts by guiding you in setting up an environment to program robots with JavaScript and Rasberry Pi 3. You will build beginner-level projects, such as a line-following robot, and then upgrade your robotics skills with a series of projects that help you get to grips with the Johnny-Five library. As you progress, you’ll learn how you can improve your projects by enabling advanced hardware components and programming concepts. You’ll even build an advanced AI-enabled robot, connect its NodeBots to the internet, create a NodeBots Swarm, and explore Message Queuing Telemetry Transport (MQTT).
By the end of this book, you will have enhanced your robot programming skills by building a range of simple to complex projects.
