License: MIT. See license file for more information but you can
7+
basically do whatever you want with this code.
8+
9+
The MY1690 has a large number of features. This example presents the user
10+
with a serial menu to control the various aspects of the IC.

MY1690X Audio Player Breakout: https://www.sparkfun.com/sparkfun-audio-player-breakout-my1690x-16s.html
15+
16+
Hardware Connections:
17+
MY1690 Pin -> Arduino Pin
18+
-------------------------------------
19+
TXO -> 8
20+
RXI -> 9
21+
VIN -> 5V
22+
GND -> GND
23+
24+
Don't forget to load some MP3s on your sdCard and plug it in too!
25+
Note: Track must be named 0001.mp3 to myMP3.playTrackNumber(1)
