Hands-On Robotics with JavaScript: Build robotic projects using Johnny-Five and control hardware with JavaScript and Raspberry Pi

Leverage Raspberry Pi 3 and different JavaScript platforms to build exciting Robotics projects

Key Features

• Build robots that light up and make noise
• Learn to work with Raspberry Pi 3 and JavaScript
• Connect your Johnny-Five projects to external APIs and create your own IoT

Book Description

There has been a rapid increase in the use of JavaScript in hardware and embedded device programming. JavaScript has an effective set of frameworks and libraries that support the robotics ecosystem.

Hands-On Robotics with JavaScript starts with setting up an environment to program robots in JavaScript. Then, you will dive into building basic-level projects such as a line-following robot. You will walk through a series of projects that will teach you about the Johnny-Five library, and develop your skills with each project. As you make your way through the chapters, you'll work on creating a blinking LED, before moving on to sensors and other more advanced concepts. You will then progress to building an advanced-level AI-enabled robot, connect their NodeBots to the internet, create a NodeBots Swarm, and explore MQTT.

By the end of this book, you will have gained hands-on experience in building robots using JavaScript
