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 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

Playing with RGB LEDs on Arduino

Introduction Regular LEDs are great, but I have such a hard time choosing the right color for a project! Sometimes one color just isn't enough. What if we could decide the color of the LED on the go? Better yet, what if we could change the color of the LED multiple times at code level,… Continue reading Playing with RGB LEDs on Arduino

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

Getting Started with Arduino: led blinking on Arduino Micro Tutorial

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 the very basics of working with… Continue reading Getting Started with Arduino: led blinking on Arduino Micro Tutorial
