The Arduino is able to output sound through a library that has been developed called the Tone Library. By creating an interface and a program that can call certain values to be output to an audio out, the Arduino Synthesizer is a robust tool for making a rudimentary noise machine. It uses granular synthesis techniques to …
Multiple synthesizer projects have been done for the Arduino, but few have been able to utilize the full power of the Arduino processor. DZL from GeekPhysical wrote a 4 voice wavetable synthesizer that is one of the more advanced software based synths for the Arduino. It has wavetables included (sine, saw, square and triangle) and envelopes to …

This simple device simple plays a small tune at a random interval, between 5 and 30 seconds when the lights in a room go off. It can be cleverly disguised inside a tissue box, or inside or under any number of household objects. This is a vary simple project (my first audio project) and requires vary few materials, most of …
I’m playing keyboards this fall in another rock concert to benefit the high school robotics team, and for some of the tunes I need to be able to fade an organ in and out over a period of a measure or two. My keyboards are velocity-sensitive, so if you hit the keys harder they play …
This is a PIR motion sensor device that works with the arduino uno. In order to make it covert enough to be placed in multiple settings and portable enough to fit most places, I decided to make the case for it appear as a speaker. The inspiration for this project: My cat is a jerk. One of his …

Have you ever struggled with audio settings in control panel in middle of a VoIP call? Or, wondered if the other guy can hear you properly? I have. My work requires great deal of remote conference calls using PC. The first thing I wonder always when starting is if my audio settings — mic volume, …
A friend of mine wanted to control Cubase, his audio recording software, with a push button so that he could stop and start recordings remotely without having to go over to the computer and type on the keyboard. You may be able to do this in other recording software, we just happen to use Cubase. Step …
This project is an Arduino-powered infrared touchscreen / coffee-table interface that I’ve been using to control various music and graphics applications on my computer. This is an old project that I’ve recently had time to go back and document/fix up; this project is a little more special to me than most because it was my …

Who doesn’t love music? These Piano Stairs are an interactive, relatively portable, musical installation that can be applied to basically any stairwell. I built them for HackPrinceton and won 2nd place in the hardware track. I’ve had requests to share my code and diagrams, so I decided to make an Instructable! These piano stairs use …
