0 本帖最后由 GerryChen 于 2016-1-28 18:16 编辑 LilyPad is a set of sewable electronic pieces designed to help you build soft interactive textiles. A set of sewable electronic modules–including a small programmable computer called a LilyPad Arduino–can be stitched together with conductive thread to create interactive gARMents and accessories. LilyPad can sense information about the environment using inputs like light and temperature sensors and can act on the environment with outputs like LED lights, vibrator motors, and speakers. Description: The LilyPad MP3 Player is your all-in-one audio solution, containing an Arduino-compatible microcontroller, MP3 (and many other formats) audio decoder chip, micro-SD card socket, and a stereo audio amplifier. Part of the Lilypad E-textiles line, this board can be used to give your fabric creations the gift of music, or any other sounds you can put on a micro-SD card. It can be powered by a 3.7V Lipo battery (charging circuit built-in!), or an external 3.5-6V source. Off the shelf, it will play specific audio files when any of its five trigger inputs are grounded, or you can solder in an RGB rotary encoder (not included) and load new firmware (included in the link below) to add a user interface for track selection and volume control! The board is compatible with sketches written for the MP3 Player Shield. Our example code uses Bill Porter’s MP3 Player library, which makes writing new code very easy. All you need to do is add a microSD card and some speakers, and you’re ready to rock. Features: ATmega 328p microprocessor with Arduino bootloader (Pro 3.3V/8MHz) VS1053B MP3 (and many other formats) decoder chip TPA2016D2 stereo amplifier MCP73831 3.7V Lipo charger (preset to 500mA, rate can be changed if desired) Headphone jack Five trigger inputs, also usable as analog, serial and I2C (“Wire”) connections Load new firmware (or write your own) using the free Arduino IDE 5V FTDI basic breakout for battery recharging and reprogramming Header for optional RGB rotary encoder (not included, requires soldering) Sparkfun link:https://www.sparkfun.com/products/11013 描述： LilyPad MP3 播放器是所有都在一个板子的音频解决方案，包含 Arduino兼容的微控制器， MP3 （以及其他格式）音频解码芯片，微SD卡插座，一个立体音频放大器，LilyPad 纺织先得一部分，这块板可以用来给你的织物创作以音乐，以及其他能够放在微SD卡内的声音。它可以用3.7V锂电池充电，或者一个外部的3.5V-6V 的电源。当五个触发输入接地的时候可以播放特殊音频文件，你可以在一个RGB翻转编码器焊接。这块板兼容为mp3播放护罩写的示意图。我们的样本代码运用Bill Porter的MP3播放器库，这使得写新的代码非常容易。你需要做的事是添加一个张microSD和一些扩音器，然后你就可以跟着音乐摇滚起来了。特征： ATmega 328p 微处理器 Arduino bootloader VS1053B MP3(和其他格式)解码芯片 TPA2016D2 立体音频放大器 MCP73831 3.7V 锂电池充电器（预设到500mA , 速率可修改）耳机夹五个触发输入，同样可以用模拟，串口，I2C链接用免费的Arduino IDE加载软件为电池充电和重新编程的5VFTDI基本模块可选择性的RGB 可旋转编码器的排插 (不包含，需要焊接) LilyPad-MP3-v15a SCH LilyPad-MP3-v15a PCB EasyEDA项目链接:https://easyeda.com/oshw/LilyPad_MP3_Open_hardware-Ujd7pjBTN EasyEDA链接：https://easyeda.com 1
