Updated Aug 4, 2011 A streamlined version is now described here. Beside the enclosure, the original feature of IllyClock is showing the time in colors: 3 hours before wake-up time, color changes from green to orange; 1 hour before wake-up, the time is shown in red. One can estimate how much sleep is left just by squinting

How’s the world feeling right now? This box tells you. Powered by: an Arduino, a WiFly wireless module, an RGB LED, Twitter.com and a 9v battery. I’m a news junkie. I want to know everything that is going on in the world as soon as it happens. I want to wake up and know immediately

In this tutorial, eight LEDs are interfaced to the Arduino Uno board. This is not complicated – it is just like interfacing a single LED to the Arduino as done in tutorial 3, but eight times over. A program is then loaded to the Arduino that will turn the eight LEDs into a “Knight rider”

In this tutorial you will connect a LCD (Liquid Crystal Display) to the Arduino Uno and then run the Arduino LCD example programs that are built into the Arduino IDE. Prerequisites It is recommended for beginners to complete all the Arduino tutorials up to and including Tutorial 10: Ten Arduino Projects for Absolute Beginners. Read
Or, an exercise in input and output multiplexing, and working with bits. And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. Parts and consumables One perf

I’ve seen a number of tutorials about how to build the platform for a 3-axis CNC milling machine. I have not seen anyone tackle the tricky subject of the electronics. Here now is my attempt to do so. Step 1: Parts You’ll need: – an arduino. I chose duemilanova. (depends on the board you get)

Like many people, I often find myself unconsciously tapping my feet, whether it’s along to a song or out of some nervous habit. As fun as that is though, I’ve always felt as if something has been missing. If only I could trigger the sounds of say, a rabid pack of furious jungle beasts instead

This cool (and very low price) sensor is attached on your ear and can detect your heart’s pulse through transmitting infrared light and checking the absorption variation caused by the blood flow on your ear lobe. The site of the products provides also the Arduino code for detecting the beats and calculating an average heart

This Instructable will teach you how to create magnetic robots that traverse vertical surfaces. These robots can move on any metallic walls, including elevators, whiteboards, refrigerators or metal doors. The robots are outfitted with several light sensors, allowing them to respond to simple user interactions. My implementation supports 3 robot ‘personalities’, which can be changed

UPDATE 1: I HAVE ADDED THE CODE FOR CONWAY’S GAME OF LIFE UPDATE 2: NOW YOU CAN SAVE SOME ARDUINO PINS WITH THE HELP OF 1 SHIFT REGISTER. In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and
