Topic: DFPlayer Mini no sound issue (Read 35 times) previous topic - next topic


I am having issues with the DFPlayer Mini, no sound output.

I am using a Arduino UNO R3. I have the DFPlayer Mini powered by the UNO using the 5v and GND pins on the UNO connected to the VCC and GND pin on the DFPlayer Mini. I have the serial connections as shown on the Wiki, TX to PWM 10/RX to1k resister to PWM 11. I then have a small 4ohm speaker connected to the two speaker connections on the DXPlayer.  I used a voltage meter and the speaker appears to be functional.

I have the audio file on a 16GM microSD card. The mp3 was created with a sampling rate of 48khz. The file is named 0001.mp3 and is located in the only folder on the card called MP3. The track is about 20 minutes long.

I am trying to run the DFPlayer full function program from the DFRobot Wiki.

Looking at the Serial Monitor, I get:

"DFRobot DFPlayer Mini Demo
Initializing DFPlayer ... (May take 3~5 seconds)
DFPlayer Mini online.

No error messages are displayed.

The blue LED blinks several times before staying solid. There is no sound at any point.
