Buying your own full-sized keyboard to create digital music can be expensive, or you may only want to experiment and fool about with some tunes - so a cheaper alternative is always welcome. One creative solution to the problem has been demonstrated by Bas von Straaten who has created a MIDI keyboard using a sheet of paper and conductive paint.
Furthermore by using conductive paint you can either recreate a classic piano-key setup - or be creative and create your own shapes that will represent each musical note. It's also great for kids as they can make a mess with it, then simply paint up another keyboard. Finally a quick demonstration of the keyboard is shown in the following video:
If you're looking to learn about Arduino and the variety of input options that are available, or just how to get more from your Arduino or compatible board, you can't go past "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more.
