This is my first time using Arduino, or any microcontroller. I’m glad it worked out so well but my wife may not be, due to the stacks of microcontrollers that will being showing up on our doorstep soon for future projects. Any feedback or questions are welcome, as are votes in the Arduino Contest. Why (Problem)

You can add Strings together in a variety of ways. This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an

ArduSniffer This Instructable shows how to build a gas detector / indicator using an arduino. The finished product is USB powered and displays the amount of detected gas on a led display. In this design the reset button on the arduino is also working. This project will cost you between €25,- and €65,- depending on

This Arduino project will display RSS feed headlines on an LCD via an Arduino and a USB cable. It works quite well, and lets you keep up with the world news while you’re sitting at your desk. Many of the values in the code can be changed, and the system can be adapted to display

Lite Brite pegs look like LED’s don’t they? That’s what I though the other day after working on an LED cube for a few hours. I happened to see my daughter’s Lite Brite sitting there, and I looked at the pile of LED’s on my desk. What a perfect match! In this instructable I will

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Inspired by Korgs Kaossilator I took it upon myself to build an opensource version of it. This way people can design new ways of interacting with the touchpad. The basic principle is creating

Arduino text‘in. Key Features: 24 relays controlled by 4 I/O lines! Cell phone text using your Arduino. This project hacks a cell phone to text using normally open relays. After investigating cellular modules on the internet I decided it looks not only rather pricy, but also like a possibility that even after I had it

The Ping))) is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3m). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. The Arduino board sends a short

Recently I’ve been posting a lot of projects that use an 8 bit resistor ladder digital to analog converter(DAC) and an Arduino to make sound. (see the Arduino vocal effects box, the Arduino drum sampler, and my audio output tutorial). The technique I’ve been using to make these DACs is very simple, it requires only a handful of 10k and

This tutorial shows you how to use a Piezo element to detect vibration, in this case, a knock on a door, table, or other solid surface. A piezo is an electronic device that produces a voltage when it undergoes physical deformation from a vibration, sound wave, or mechanical strain. Likewise, applying voltage to a piezo
