Each glass has a different amount of water and produces a different note when tapped. [Cyberlab] must have seen them and created an Arduino robot to play tunes on glasses.

To generate these signals, I used an Arduino. One of the greatest challenges of the project was creating an analog output that was fast enough to move the galvo (and laser beam) so that it ...

[MrRedBeard] wanted to play a particular song from an Arduino program and got tired of trying to hand transcribe the notes. A little research turned up that there was a project to convert Music XML… ...

Each Arduino mimics a different instrument: one plays the bongos, another plays the bass, and the third plays the snare drum. It’s like training wheels, for beat-boxers.

Meet Primo: a physical programming interface that teaches children programming logic while they control the movements of an Arduino-powered robot. All of Primo's electronics are concealed inside ...

The sensors trigger an Arduino to turn on LEDS on a nearby setup. In the video (which is after the break) you can see the entire thing in action -- which maker Joe says can eventually lead to a ...
