Providing both MIDI-IN and MIDI-OUT connections, the MIDI Shield board gives your Arduino access to working with musical equipment, so you can control synthesizers, sequencers, and other musical devices. Its protocol shares many similarities with standard asynchronous serial interfaces, so you can use the UART pins of your Arduino to send and receive MIDI's event messages.
This shield can be mounted directly on top of an Arduino, connecting the MIDI-IN to the Arduino's hardware RX pin and the MIDI-OUT to TX. Potentiometers are connected to analog pins 0 and 1, and can be used to control volume, pitch, tone or anything else you'd like. Also connected on the shield are three momentary push buttons (connected to D2-4), a reset button, and green and red stat LEDs. The RUN/PROG switch allows you to program the Arduino over serial without having to remove the shield.
