Description

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 you through 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 JohnnyFive 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 JohnnyFive 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

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

Andrew Connell Dec 18, 2015

I'm a seasoned JavaScript developer and aspiring hardware guy for my own personal projects. Having heard Kassandra on a podcast episode or two, I wanted to pick this book up. I found it very easy to grok and pickup the concepts. I am more of a Raspberry Pi guy and all the projects used the Arduino Uno - my only "complaint" that it should have been more visible in the marketing / cover - however I walked away placing an order for the Uno, something I've wanted to learn! All the projects were super simple to understand and implement... as a tech author I know how much work goes into this, but hoping for something that goes even deeper for her next work!

This book is a great way to "break in" to JavaScript Robotics with Johnny-Five. Each chapter walks you through the basics and then illustrates how to build something with with what you've learned—which is a great strategy!

Roberto M. Pensotti Apr 19, 2017

If you want to learn programming for robots, or micro controllers in general, this is the book.JavaScript on NodeJS is the best language for this type of application.Well illustrated, well documented..Excellent!

K Feb 11, 2016

This book assumes quite a bit less of your robotics experience than it does of your experience with JavaScript. It focuses a great deal on the excellent Johnny Five library for Raspberry Pi and Arduino. It helps you to learn the basics of motor control as well as sensor information through GPIO. If you already have JavaScript experience, this is definitely the best foray into extending your ability into the world of robotics.

Grayson Nov 30, 2015

The animation chapter alone makes this a great book. Great introduction to nodebots and generally working with electronics + javascript. Presented in an approachable manner with clear explanations.
