I’m not sure if I agree that the Keytar is the world’s sexiest instrument, but this still a really cool project. It’s a keyboard/guitar controlled by an Arduino. The website has a little more information about the build and you can download the Arduino code.
Which is the worlds sexiest and awesomest instrument? yes, the keytar. But what if you want special features on it and are to cheap to buy one of ebay? That is what I am. Cheap and special, that is why I made my own.
