hello. I am a design student who knows nothing about coding or Arduino. I desperately need your help! I’m doing now my own project with textiles and Lilypad mp3. I have two questions: When making a sound using a lily pad, there is a delay of about 3 seconds. Is it possible to eliminate the delay? And can I make different sounds overlap when I touch both parts(ex. T1 and T2 Together) at the same time? What part should I modify in the original Arduino Lilypad mp3 file? Any help would be greatly appreciated.
Thank you so much for your reply! I have another question to your answer, I hope it will be okay. The SD card I am currently using is a SanDisk Ultra SD card. If I use Extreme or Extreme Pro, which is one or two steps faster than this, will the response speed go up even further?
And when I looked at the attached link, I saw that it is a board that needs to be soldered. Would it work if I used a conductive thread like the Lilypad mp3?
thank you so much! I’ll be waiting for your reply. Have a nice day!
I don’t think a three second delay will be resolved with a faster SD card. There could be a problem with the one you’re using but rated R/W speeds probably aren’t the bottleneck.
I agree with Brow, and I think it’s your MP3 files. Make sure your files are “clean” and contain no metadata or images. If those are present, the board attempts to play them causing a delay until the board gets to the part of the file that contains the actual audio data.
I believe the software Audacity has a setting to remove metadata from mp3 files.
Hi, Everyone! Thanks for the replies! Actually, when I connected a fast SD card, the delay disappeared. Originally, my mp3 file had no metadata other than audio data.
Anyway, I’m gonna try using a different trigger board and conductive thread instead of soldering.
