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… Continue reading How to communicate with an Arduino via Serial using PHP code

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

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 I confess I was/am a bit outdated on what's going in the PHP world nowadays, so I wasn't quite sure of which version is the… Continue reading Installing PHP 7.1 on Raspbian Stretch (Raspberry Pi Zero W)

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

How to Build a Candle Light LED Lamp (flame effect) with Arduino Micro

Introduction LED lamps are usually quite easy to build, and using simple materials you can create really fun effects. But what about an LED lamp that simulates the flickering effect of a candle light? There are LEDs which have a "built-in" flickering effect, and there are also ways to create this effect at circuit level.… Continue reading How to Build a Candle Light LED Lamp (flame effect) with Arduino Micro

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

Fade / Pulse effect with Arduino Micro: video tutorial

The Arduino Micro is a very compact microcontroller board based on theĀ ATmega32U4 microcontroller. It's super handy for small projects, and the good thing about Arduinos is that they have a bunch of compatible stuff you can find rather easily on the market, and they have less moving parts compared to a Raspberry; however, you have… Continue reading Fade / Pulse effect with Arduino Micro: video tutorial
