How to build an Air Guitar with Arduino, aka the AIRduino Guitar
The idea here is to build a wearable virtual guitar that is to be controlled with two hands much like playing Air Guitar. It has been created and prototyped during a two weeks project at ChalmersUniversity (Sweden) for a Physical Computing class.
The aim is to get the feeling of playing a real guitar. The AIRduino Guitar is made of one glove and one stick. The glove is used to set the tone and the stick to trigger the sound.
To perform such trick, we used an accelerometer and an ultra-sonic sensor (see Step 1 for concept description).
Take a look at the video demo to get a more precise idea of how it works, and get to work to build your own!
Arduino noise box synth | mechomaniac
As my first Arduino project, it was a bit of an experiment with the Arduino programming environment, and I also wanted to investigate direct Audio synthesis using PWM on the Arduino. The basic sequencer concept came from the Arduino Punk Console, while synthesis was adapted from the Atmega SID Project.
The basic features are:
* 16-step programable sequencer with adjustable frequency and duration for each step
* synthesizer with 4 output waveforms (sine, square, triangle and sawtooth)
* noise generation (sirens, laser beam, random noise)
* special random sound modes
The user interface is kept very simple, with just four knobs, three puss buttons, 8 LEDs and a power switch. The speaker is connected straight to a pin on the Arduino via the volume knob - everything is done in the Arduino using PWM to generate analog waveforms. The LEDs indicate the current step in sequencing mode, and provide light patterns in noise modes.

Cantarino is a software speech synthesiser for Arduino. It is still a work in progress, but a tech demo that runs on Arduino is now available.

Sound is generated by playing the same noise ('grain') repeatedly at very high speed. This merges into a tone that is an audible hybrid of the repetition rate and the original grain. It sounds quite similar to an oscillator with two resonating bandpass filters, although the different architecture means there are lots of additional interesting noises at parameter extremes.
The grain consists of two triangular waves of adjustable frequency, and adjustable decay rate. This is based on FOF synthesis model, but using triangle waves instead of sine and using a rectangular window.
The repetition rate is set by another control.

The Arduino is a little programmable doo-hickie that can be used for lots of things. I was playing with mine recently and hooked the digital outs up to an analog sound board. This is a common thing to do with the Arduino. You can coax the thing into making analog-like sounds through the digital output. Since it is digital, everything is a square wave.
Lab3 - Labor für experimentelle Informatik
This is an experiment to show how some realtime audio processing can be done with the Arduino. The first set of examples alter an incoming audio signal and put it back to an audio output. We achieve effects like Reverb, Phasor, Flanger or Ringmodulator. The second set of examples are outputting computed waveforms like Sinewave, Bell and Xylophone sounds.
Making Simple PVC Flutes
This flute design is a common one on the net, and for good reason. Not only is it simple to build, it's also relatively simple to learn and rewarding to play. It only took a month of on and of playing to be relatively proficient (meaning I could get a clean sound from the first two octaves without difficulty.) The flutes are keyed instruments and only play in one scale (without more complex fingerings) which is actually a plus when just noodling around since you can't easily hit a note outside of the major scale of that flutes key.
My G flute can hit about 2 octaves easily and 2.5 octaves if you push it. My D fife can hit 2 octaves. There are already a number of good sites out there on how to make flutes, but I thought I would add some of my experiences making my own flute collection that haven't been addressed.
A simple light to sound converter - with video !
This a simple circuit I designed and built to convert light variations into sound. It is fun to listen to the weird sound emitted by the light of remote controls, light bulbs, TV screens and any light source.

One of my projects for last week’s 24h Thesis was this noise-generating box. It has two speakers, four buttons and two potentiometers mounted on a cardboard box and connected together with a breadboard and an Arduino. Each button has a different sound, which can be modulated with the two potentiometers. It sounds like this:

The Arduino — the Freeduino to be exact, in this illustration — is an ideal, basic platform for experimenting with electronics and microcontrollers. It can be thought of as a very simple, open source computer for use in making devices you make up. It’s pretty basic for sonic work, but for some, that’s its appeal. Photo: George P. Macklin; see granularmatter.com.
Felt and circuits: Critter and Guitari have made a synth-ready shield for the Arduino that turns your electronics into a usable, squelchy synth. But it’s not complete until you painstakingly handcraft an enclosure from felt, as photographed by the creators. For more felt and circuits, see our interview with Monome creators Brian and Kelli, who moonlight as lovers of sustainable fabrics.
I received my Arduino Diecemila in the mail last week and have started to experiment with using it to synthesize audio and video. I’m not very experienced with programming microcontrollers, so I’ve been doing a lot of research to see what’s out there, and it’s greatly encouraging to see that people are taking this little kit in fun directions.
While I wasn’t able to find many “finished” projects, I did find a whole lot of ideas that deserve further exploration:
First up is a simple but effective “Arduino Theremin” from Alberto Bietti. Looks like this one uses an ultrasonic rangefinder rather than an RF field to effect pitch. The squelchy FM-like tone is a little screechy but could work well with a little bit of filtering:
