You can easily change these settings if desired, or make any other changes you wish to the sketch, by using the free Arduino programming environment. Ease of use Proprietary Bose technologies automatically perform many of the adjustments needed for high-performance audio. So you can enjoy the performance of a large, multi-component stereo without a row of controls. Connect your 5V FTDI board or cable to the LilyPad MP3 Player. (The yellow “charge” LED may light up, that’s fine.) Turn on the LilyPad MP3 Player’s power switch. Right Speaker + Right Speaker + Connect to the right speaker + terminal.
That is there to allow you to add an optional RGB rotary encoder if you wish. Since this data is at the beginning of the file, the VS1053 chip had to read through (and ignore) all the image data before getting to the actual audio data. Unregulated 3.7V to 6V source If you have an external 3.7V to 6V source, you have two options: If you want to use your power source to recharge an attached Lipo battery, you can attach it to the “VIN” sew tap.
The board contains a power switch that is used to turn the board on and off. Triggers Electrically, we’ll be connecting each trigger to a momentary switch, with the opposite side of the switch connected to ground. From the IDE’s “Tools/Board” menu, select “Arduino Pro or Pro Mini (3.3V/8MHz) w/ATmega 328” From the IDE’s “Tools/Serial Port” menu, select the port that your FTDI board or cable is using. Serial MIDI connection (SJ3) SJ3 (on the bottom of the board) can be used to connect the serial RX line (trigger 5) to the serial RX pin of the VS1053B audio decoder chip. For much more detail see the VS1053B datasheet. MPEG layer III (.MP3) Two channels max Sample rates: 8 through 48 kHz Bitrates: 32 through 320 kbit/s Variable bit rate (VBR) supported Layer I and II also supported with additional setup, see the VS1053B datasheet for more information.
