Sound Reactive LED Strip

THERE MAY BE 9 STEPS BUT I PROMISE THIS ONE IS QUICK AND EASY!  In this Instructable I will be showing you how to create a light reactive LED system. In this clip, I used a single color LED strip, but you you can use a single LED, multiple LEDs wired together, single color or RGB LED strip, it just depends on what you are trying to build. The set up is fairly simple, the component list is fairly basic so if ...

Twitter Enabled Text to Speech using an Arduino

Let the world know what you're eating for breakfast with an 80's style vocal synthesizer!  This project uses an Arduino to send your Twitter stream to a voice generator chip called the SpeakJet.  The setup that I use here can also be extended to other applications where you'd want to translate text into speech, some ideas: -a robot which announces things or responds to its environment by speaking -some kind ...

Breathalyzer Microphone using an Arduino

The breathalyzer microphone is a system for the inconscpicuous collection of blood-alcohol content level data sets. In other words, you can measure a person's sobriety with a device, that for all intents and purposes, looks no different than a standard microphone. This tool adds new dimensions of truthiness to any standard interview. It can also easily be adapted for karaoke. Don't be intimated by the numbe ...

Arduino Personal Soundtrack Hoodie

This was inspired by Raj's personal soundtrack shirt in Big Bang Theory S3, E16, "The Excelsior Acquisition". You can now buy them online but it's much more fun to make your own and it's possible now that buttons designed for use in electronic clothing are available from Connectedwear. Nine of the buttons on the Connectedwear keypad sewn into the hoodie's arms each play a given sound or tune and the tenth a ...

Arduino Vocal Effects Box

This Arduino-powered vocal effects box pitch shifts and distorts incoming audio signals to produce a wide variety of vocal effects.  This project is my first experiment with real-time digital signal processing using Arduino.  It samples an incoming microphone signal at a rate of about 40kHz, manipulates the audio digitally, and then outputs 8 bit audio at 40kHz.  To minimize the amount of computation requir ...

Make a Musical Bench using Arduino

The Musical Bench is an exhibit which makes music when people touch, kiss, or hold hands. It uses a micro-controller to detect changes in resistance, via the copper armrests, and plays high or low notes depending on how much current flows through you and a friend. This exhibit is the result of messing around with many different ways of using the human body to complete an electrical circuit. The original Exp ...

Musical Exercise: Workout Shirt MP3 Player Powered by Exercise using Arduino

People love listening to music while exercising. Music provides the motivation needed for individuals to keep exerting energy and get in shape. So, because people enjoy listening to music while exercising, what if an MP3 player only played an individual's music while they are active? Using music as an incentive to continue exercising would encourage individuals to work harder and remain motivated in order t ...

Turn your Arduino Uno into an USB-HID-Mididevice

While building an Arduino Uno based Midi-Controller for Ableton Live, I came across the HIDUINO project ( http://code.google.com/p/hiduino/ ). It allows you to turn your Arduino Uno (or any other device using an AVR-USB chipset like the 8u2) into a driverless HID/Midi device. It's much more comfortable than using a software based serial to midi converter which has to run in the background all time. The only ...

Building a Portal Turret with motion controlled audio and lighting

In this Instructable I'm going to show you how I went about building my very own life size talking Portal Turret from start to finish. This is a fairly in depth project that will cover every stage of construction and all the techniques I used along the way. Hopefully there will be a lot of information that you can pull out of this and use for all kinds of different projects. For those that are unfamiliar wi ...

Step Sequencer Drum Machine

Overview [top] As avid audiophiles, we wanted to apply our newly acquired knowledge of microcontrollers to build a fun consumer electronic device. Our project is a step sequencer drum machine. The user is able to program a 16-step percussion pattern using one of a wide range of percussion instruments on each of six different tracks. The user toggles between different tracks and different instruments and adj ...

Stereo Audio with an Arduino

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 20k resistors wired together into a network.  But the convenience come ...
