Description

Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It's low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.

This shield is a kit, and comes with all parts you need to build it. Arduino, SD card, tools, speaker and headphones are not included. It is fairly easy to construct and anyone with a successful soldering project under their belt should be able to build it.

The shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when serial data is received, etc. Audio is played asynchronously as an interrupt, so the Arduino can perform tasks while the audio is playing.

Can play any uncompressed 22KHz, 16bit, mono Wave (.wav) files of any size. While it is not CD quality, it is certainly good enough to play music, have spoken word, or audio effects. Check out the demo video/audio at the webpage
Output is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker that is switched on when the headphones are unplugged
Files are read off of a FAT16-formatted SD/MMC card
Included library and examples makes playing audio easy
Please note that the library is rather bulky, requiring 10K of flash and more than 1/2 K of RAM for buffering audio. It works fine using an ATmega168-based Arduino (or compatible) but for more complex projects I strongly recommend upgrading to an ATmega328!

描述

添加品質音頻電子項目是相當困難。這裡為Arduinos屏蔽，解決了這一問題。它可以播放長達有22KHz，任何長度的12位未壓縮的音頻文件。它的成本低，可作為易於化妝試劑盒。它具有高品質的輸出板載DAC，濾波器和運算放大器。音頻文件讀出一個SD / MMC卡，可在幾乎任何商店。量可與機載指輪電位進行控制。

這盾是一個工具包，並配有你需要構建它的所有部件。 Arduino的，SD卡，工具，揚聲器和耳機不包括在內。這是相當容易的構建和人與他們的皮帶下一個成功的焊接項目應該能夠建立它。

屏蔽帶有一個Arduino庫，方便使用;只需將未壓縮的波形文件到SD卡並將其插入，然後使用該庫來播放音頻時，按下按鈕，或者當傳感器熄滅，或接收到的串行數據時，音頻等異步播放作為中斷，所以Arduino的可以在音頻播放執行任務。

可以播放任何未壓縮的有22KHz，16位，單聲道波形（.wav）任意大小的文件。雖然它不是CD音質，那肯定是不夠好，播放音樂，所講的話，還是音頻效果。退房的演示視頻/音頻的網頁
輸出為單聲道，成L和R通道，標準的3.5mm耳機插孔和揚聲器的連接就是當耳機被拔掉接通
文件被讀出一個FAT16格式的SD / MMC卡
包括庫和示例使播放音頻方便
請注意，該庫是相當笨重，需要閃光的10K和1/2以上的K的RAM用於緩衝的音頻。它工作正常使用基於ATmega168的-的Arduino（或兼容），但對於更複雜的項目我強烈建議升級到ATmega328！
