Inspired by MAKE and the Stylophone my first non blinkey light Arduino project. It is a 1 octave midi keyboard. The keyboard is etched circuit board wired up to the Ardunio using the pull up resistors on the board. The stylus is ground. Touch the note with the stylus and it send midi opt code out of the Arduino serial pin. The midi port is wired right into the serial, ground and +5. Not to spec but it works.

If you didn’t want to buy a synth for the project you can use the USB to control Pure Data software synths or put a little speaker on a PWM pin and make some square wave sounds (very much like the original stylophone). Code, more details and other MIDI projects to come!
