SparkFun MIDI Shield SF_Buttons and Switches it remains in a floatingThe SparkFun MIDI Shield board gives your Arduino based device access to the antiquated, but still widely used and well supported [MIDI communication protocol](http: en. wikipedia. org wiki Musical_Instrument_Digital_Interface), so you can control synthesizers, sequencers, and other musical devices. The MIDI protocol shares many similarities with standard asynchronous serial interfaces, so you can use the UART pins of your Arduino to send and receive
