Embedded Systems What do you think of when you hear the name Laravel? Laravel 4 powers an increasing number of websites, but that’s not the only place it can be used. In this tutorial we’re going to use it to control embedded systems. . The code for this chapter can be found at: https://github.com/formativ/tutorial-laravel-4- embedded-systems. Gathering Parts This tutorial demonstrates the use of an Arduino and a web cam. There are other smaller parts, but these are the main ones. The Arduino needs firmata installed (explained later) and the webcam needs to be compatible with Linux and Motion (installed later). We will go over using things like LEDs and resisters, but none of those are particularly important. We will also go over using servos and these are important. You can find the bracket I use at: https://www.sparkfun.com/products/10335 and the servos I use at: https://www.sparkfun.com/products/9065. You can get these parts, and an Arduino Uno, for less than $55. Installing Dependencies We’re developing a Laravel 4 application which has lots of server-side aspects; but there’s also an interactive interface. There be scripts! For this; we’re using Bootstrap and jQuery. Download Bootstrap at: http://getbootstrap.com/ and unpack it into your public folder. Where you put the individual files makes little difference, but I have put the scripts in public/js, the stylesheets in public/css and the fonts in public/fonts. Where you see those paths in my source code; you should substitute them with your own. Next up, download jQuery at: http://jquery.com/download/ and unpack it into your public folder. For the server-side portion of dependencies, we need to download a library called Ratchet. I’ll explain it shortly, but in the meantime we need to add it to our composer.json file:
Embedded Systems 288 1 "require" : { 2 "laravel/framework" : "4.0.*", 3 "cboden/Ratchet" : "0.3.*" 4 }, . This was extracted from composer.json. Follow that up with: 1 composer update . Ratchet isn’t built specifically for Laravel 4, so there are no service providers for us to add. We’ll now have access to the Ratchet library for client-server communication, Bootstrap for styling the interface and jQuery for connecting these two things together. Note About Errata I love all things Arduino and Raspberry Pi. When I’m not programming; I’m trying to build things (in the real world) which can interact with my programming. Don’t let that fool you though: I am not an expert in electronics. There are bound to be better ways to do all of this stuff. If you can’t get a specific program installed because apt or permissions or network settings or aliens; I cannot help you. I have neither the time nor the experience to guide you through the many potential problems. Hit me up on Twitter and, if I have not yet already done so, I will connect you to a forum where you can discuss this with other (smarter) people. Creating An Interface The first step to creating an interface is returning static HTML for a web request. We handle this by creating a route, a controller and a view:
