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 ...

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… ...

Then you encode each note as a number from 0 to 6. Of course, you also have to fill your glasses with the right amount of water. A piano tuning phone app should be useful.
