This proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He&#8217… ...

Hi, It is a simple project to play an audio file in the SD card using Arduino UNO. For this, audio file must be in .wav format and has sampling rate of 16000Hz and 8bit resolution.

Arduino board programmed with an audio file Programmer Mike Tsao has devised a clever method to program an Arduino board using sound.

This p5js sketch receives a track number from an Arduino microcontroller and plays that sound. There is an example Arduino program in the arduino folder (written using PlatformIO, but it will work ...

[MrRedBeard] wanted to play a particular song from an Arduino program and got tired of trying to hand transcribe the notes. A little research turned up that there was a project to convert Music XML… ...

The SoundDuino Arduino sound shield is capable of working with voltages from 3.3v to 5v and if you use the other Arduino boards, the only pins that you require are GND, VCC, RX, TX.

To learn more about the handy Arduino sound card, you can watch the video above. The SoundDuino 2 has taken to Kickstarter to raise the $2,000 required to make the jump into production.
