Time to build your real-time MIDI instrument/music player! The Music Shield is an audio encoder/decoder compatible with Arduino, Seeeduino, Seeeduino Mega and Arduino Mega. It is based on the VS1053B chip, which enabled it to play sound files from SD card and do short-time recording as well. You can also use it to play MIDI notes by slightly changing its hardware installations. Due to the SPI communication mode, it keeps a minimum number of IO port that facilitates users’ own developments of this device. Additionally, the new multifunction button provides greater convenience for users to control.
