Hands-On Robotics with JavaScript

By: Kassandra Perch

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.

Questions


  1. What does PWM stand for, and what does it accomplish with LEDs?
  2. Does the Raspberry Pi have any PWM-capable pins? How many?
  3. Why do we need a GPIO expander board to control our RGB LED?
  4. How many colors would our RGB LED be able to show without PWM?
  5. What protocol does our GPIO expander use to communicate with the Raspberry Pi?
  6. What does the color module do for us?
  7. How does the REPL help with debugging? What makes it so powerful?
