Preface

By Rick Waldron

I love programming and I also love making things. When I discovered Chris Williams’ node-serialport module (for Node.js), I remember thinking, “Now I can program the things that I make.” So I did! I contributed an Arduino sketch that printed a photoresistor sensor value to the open serial port and a small JavaScript handler program that listened for data and printed a “graph” to the terminal. Months later, I started contributing to Cam Pedersen’s duino project, until Julian Gaultier approached me with his JavaScript implementation of the Firmata protocol. From there, we set out to build a collection of high-level component classes with one goal: to make it easy and fun to control hardware with JavaScript. This book will ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
