Little variations are caused by the noise. Take note that if there isn't an audio signal the read will be about 512 because to have an audio signal between 0 and 5V we need an offset of 2.5V. 12.08.14 17:43:29,000 kernel: USBF: 2718.835 AppleUSBEHCI::DoControlTransfer sync request on workloop thread. Now we can simply read the analog input in this way. Offers the ability to decode and play MP3 audio files from mass. Hope you enjoy it Beginner Full instructions provided 4,350. Ha, i missed copying the first line from the OS X console. EasyMP3 Shield is an Arduino frontend that provides integrated MP3 hardware decoding. This is a cool way to measure your hearing. Do you see a chance of getting this to work by tweaking some numbers in your files?ĭo you have more information on this project out there or got it any further? It feels like you've been overseen for a while. Which OS are you using?Īt this point, i really don't mind audio quality. I also gave it one try on a win 7 laptop with no better results after letting it search & install drivers for the Leonardo. The OS X Console shows something like this: 12.08.14 17:45:32,000 kernel: AppleUSBCDCACMData: Version number - 4.2.1b5, Input buffers 8, Output buffers 16ġ2.08.14 17:45:33,000 kernel: USB Sound assertion in AppleUSBAudioDictionary at line 2927ġ2.08.14 17:45:33,000 kernel: USB Sound assertion in AppleUSBAudioDictionary at line 1389ġ2.08.14 17:45:33,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 6049ġ2.08.14 17:45:33,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 364ġ2.08.14 17:45:33,000 kernel: USB Sound assertion in AppleUSBAudioDevice at line 286 3 Arduino Ethernet Shield 2 Arduino Gemma Arduino GSM shield V2 Arduino IDE Arduino IoT. Unfortunately this Macbook still won't list the Leonardo as an audio device. I'd really like to get this working.Īfter patching a brand new Arduino IDE (1.0.5) with your files, your example sketch compiled and uploaded with no errors and runs fine (printing to serial console). I found your post this morning an gave it a try on OS X. Here's a complete parts list: 1 ea Arduino Duemilanove or equal ( Radio Shack 276-128 Arduino Uno REV3 will work also) with power adapter 1 ea Arduino Proto Shield (Radio Shack 276-140 is slightly different but will work) 2 ea Phone jacks (Mouser 161-3508-E) 1 ea Terminal block, 5.08mm (Mouser 651-1935561) 1 ea Tactile PB switch (DigiKey SW407.
