How to communicate with an Arduino via Serial using PHP code

Introduction I recently got my hands on a 7-segment display module (always wanted to play with those!) for a little project and at first I wanted to use purely PHP on a Raspberry Pi Zero to control it. However, due to lack of time (and a touch of lazyness) I ended up using an Arduino with the default library associated with this module (TMI637.h), and while looking for ways in which I could send data to the display through PHP code I figured it was really easy to use serial c

How to create a simple IOT device with PHP on a Raspberry Pi Zero W

Introduction Following on the “PHP on Raspberry” train, I wanted to create something simple enough to use as a demo, however it should be useful and it should include some simple components to show how easy it is to build a little gadget using PHP on Raspberry. I’m not gonna go into detail about “why PHP” and I also won’t enter any language shaming discussion – that being said, just keep in mind, in case you don’t know this yet, that modern PHP is a cheap, accessible and popu

Installing PHP 7.1 on Raspbian Stretch (Raspberry Pi Zero W)

Introduction On my last tutorial, I showed how to use Ansible to automate the setup of a Web Server running PHP 7 on a Raspberry Pi Zero W (running Raspbian). I confess I was/am a bit outdated on what’s going in the PHP world nowadays, so I wasn’t quite sure of which version is the most recommended or compatible with the newest stuff. After digging around a bit in order to perform some benchmarks and just general research on the web server setup, I figured I’d need PHP 7.1 to

How to use Ansible for setting up a Raspberry Pi Zero W Web Server with PHP 7

Introduction The Raspberry Pi Zero W is a small (and affordable) computer on a board – it has the essentials for creating little projects with built-in wi-fi, an HDMI output and an extra USB for input from a keyboard or mouse. It runs a Linux distribution (Raspbian) and for that reason it’s very versatile and user-friendly, since we can use pretty much any programming language that can run on Linux. Apart from that, of course, you have the GPIO pin head to create circuits and

Adafruit’s Perma Proto Bonnet Mini Kit – hands on

After finishing the breadboard prototype of our little Raspberry Pi Zero W Audio Streamer, I wanted to move the prototype to a nicer “home”, making it small and easy to carry on travels – we planned on using it as a travel-friendly baby monitor. So after evaluating the options, we decided to make a little Bonnet using Adafruit’s Perma Proto Bonnet Mini Kit. What is a Bonnet? Well, it’s a little hat 😉 seriously thou, in Raspberry terms, a bonnet is a small board add-on (liter

Getting Started with Raspberry Pi: LED blinking on Raspberry Pi Zero

Introduction LEDs are probably the best thing that ever happened in electronics, they go well with absolutely everything (like raisins, pretty much) and as it turns out, they’re pretty simple to work with. That’s why they’re just perfect for any beginner tutorial on electronics. This tutorial will show you how to control an LED from a Raspberry Pi Zero. We’ll be using Python to control the LED – it is definitely possible to use a variety of programming languages for that, but

Audio Streaming with Raspberry Pi Zero W and Adafruit’s I2S Mic

The Raspberry Pi came to revolutionize the world of makers alike. Unlike Arduino, the Raspberry Pi runs a whole Linux distribution on it (Raspbian) and allows you to work with software in a much higher level. You can use pretty much any programming language to create whatever you want. You can even use its graphic interface, and still connect with low-level components through its I/O pins. This tutorial turns a tiny Raspberry Pi Zero W (with built-in wireless) into an audio s

Raspberry Pi Zero – Unboxing and Initial Setup

The Raspsberry Pi Zero is the smallest and cheapest member of the Raspbery Pi family. It’s cheap and powerful enough for a handful of funny and interesting projects! The version without wireless costs about 5 euros and the version with wireless costs about 11 euros, prices from Amsterdam stores. Here are the full specs, from the official blog announcement: A Broadcom BCM2835 application processor 1GHz ARM11 core (40% faster than Raspberry Pi 1) 512MB of LPDDR2 SDRAM A micro-S
