When sound is detected the DFPlayer must stop playing or pause. Im currently working on a project to play random audio tracks when no sound is detected, the random track played when there is no sound MUST start from the beginning. Is anyone know a samples player module, cheap and i2c controlled ? If your sample start immediately, probably no hear this 'clap' but it there is a silent before, a 'bad clap' is announcing the sample. It i put volume to 0 (0-30) i always have this 'clap'. I always have a 'clap' sound at startup playing sample, It's a pain to organize the mp3 on sdcard. You can name the files as you want, it doesn't care. The DFPlayer doesn't care of files names, it play files as they are in folder structure. If i ask to play file name 023, it play 024.mp3. If i send a command to DFPlayer to play sample 001 to 022, it play 001.mp3 to 022.mp3 but,

I put 43 mp3 on SDcard, the 43 numbers of a darts games.

Today, i want to try playing files named 001.mp3, 002.mp3, 003.mp3. wav, the 'clap ! sound' at start playing isn't as high.īur for looping sample, i think it can be a problem. I think i can reduce wait time between serial commands. I create 'reset' fonction and i do this at boot time.Īnd it boot fast, no bug. Name as you want and create folders but : Uint8_t play1 = įor (int i=0 i I have a question for you: Is it a requirement that the files are named like 1.mp, 2.mp3, 3.mp3 etc? Or can you also use names like songa.mp3, songb.mp3 etc. SoftwareSerial mySerial(10, 11) // RX, TX I don't use any DFPlayer library for playing samples with DFPlayer.

samples names are not only xxxx.mp3 (copy/paste mp3/wav on SDcard and play.

All samples i try are playing by DFPlayer (22khz, 44khz, wav, mp3).

USE 5V (external power supply, i use 5v 2a) to power DFPlayer.TTL is 3.3v so USE 1kOms between (Arduinot TX) and (DFPlayer RX) (i will try level shifter) cd4050.If you power down the DFPlayer, do it 5 seconds mini.Use external Power to try DFPlayer, don't works with 5v supplied by Arduino.1st library i found is very very incomplete.folder names 001, 002, 003, but news library use folder 'mp3'.I read everything I could find on the DFPlayer but the information is contradictory.

(must use 100% volume or sound isn't perfect). Sound at 100% (30/30) is nice but sound at 35% (10/30) or others is crackle.Easy to crash if you send commands too quick or.random crash/random start.Time to boot is random, i don't know why sometime it take 1s, some time 20s.So, use le news library and/or use Software Serial is recommended. It's very very boring but i know this problem (as serial bluetooth module and others serial devices). You MUST unplug RX/TX for upload to Arduino. It's a pain to use this module with RX/TX from arduino (Hardware Serial).3 days i'm working with this DFPlayer and.

Amazing audio player module
