First and foremost, big thanks to Damien for her time and effort on soldering 265 LEDs on peggy2 circuit board, which made my programming part possible to continue. Instead of soldering LEDs directly onto the Peggy2 board, we have to use Ethernet cables as “extensions” in order to let LEDs fill our smart surface. Single

Today we are going to examine the Maxim MAX7219 LED display driver IC. The reason for doing so is to show you how something that used to be quite complex can be made very simple – and that is what all this technology is for, isn’t it? If you have ever tried to control lots

Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible. I built this as a table top or wall mount model, but it can be scaled up to make a coffee table. I built it as a study for a more ambitious project, which

Use the Maxim MAX7219 LED display driver with Arduino in Chapter 56 of our Arduino Tutorials. The first chapter is here, the complete series is detailed here. Update – 4/1/15 – This article is pending a re-write, please refrain from comments and questions until the new version is published. Introduction Sooner or later Arduino enthusiasts and beginners alike will come

After buying a Nanode (an Arduino-compatible board with ethernet built-in) last weekend, we’ve been trying to work it out by making a couple of simple examples, the ‘Binary Dice’ is the first one with input and outputs. A note, this code example is based on the one from the book Arduino: A Quick-Start Guide by

Now with more LED. Arduino mega powered breathalyzer using the MQ-3 sensor. A relative gauge for judging how intoxicated you are. NOT TO BE USED AS MEANS OF BREATHALYZING NEVER DRINK AND DRIVE. This is more of a device to encourage one to drink more. The MQ-3 can’t achieve the accuracy to register exact

This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield. The project was originally inspired by a friend wanting to make a “sexting themed” costume, with a scrolling LED display of live texts sent from people at the party. We

Have you wanted to make a sweet Cylon/Knight Rider (Larson) Scanner effect? But you don’t want to use up all of your Arduino IO pins? Well, you can make a nice 8 LED Scanner with a shift register IC. In this tutorial we’ll be using the 74HC595 8 Bit Shift Register, and this is what

The 3D LED Cube is a really cool device that enables you to see in three dimensions, get some depth perception and has 512 LED’s or 512 pixels. It is based on an Arduino Uno which is an Atmel AVR microcontroller on a development board with some standard interfacing pinouts that allow you to quickly
