Learning JavaScript Robotics

English | 2015 | ISBN: 978-1785883347 | 160 Pages | EPUB, AZW3, PDF (conv) | 10 MB

Design, build, and program your own remarkable robots with JavaScript and open source hardware
There has been a rapid rise in the use of JavaScript in recent times in a variety of applications, and JavaScript robotics has seen a rise in popularity too. Johnny-Five is a framework that gives NodeBots a consistent API and platform across several hardware systems.
This book walks yout hrough basic robotics projects including the physical hardware builds and the JavaScript code for them. You’ll delve into the concepts of Johnny-Five and JS robotics.
You’ll learn about various components such as Digital GPIO pins, PWM output pins, Sensors, servos, and motors to be used with Johnny-Five along with some advanced components such as I2C, and SPI. You will learn to connect your Johnny-Five robots to internet services and other NodeBots to form networks. By the end of this book, you will have explored the benefits of the Johnny-Five framework and the many devices it unlocks.
What You Will Learn

• Familiarise yourself with Johnny-Five Read, Eval, and Print Loop (REPL) to modify and debug robotics code in real time
• Build robots with basic output devices to create projects that light up, make noise, and more
• Create projects with complex output devices, and employ the Johnny-Five API to simplify the use of components that require complex interfaces, such as I2C
• Make use of sensors and input devices to allow your robotics projects to survey the world around them and accept input from users
• Use the Sensor and Motor objects to make it much easier to move your robotics projects
• Learn about the Animation API that will allow you to program complex movements using timing and key frames
• Bring in other devices to your Johnny-Five projects, such as USB devices and remotes
• Connect your Johnny-Five projects to external APIs and create your own Internet of Things!
