    • 1. Example Code for Arduino-Recording

    This article demonstrates the setup and coding required for an Arduino voice recording project using the DFRobot DF1101S library and hardware components. It includes hardware preparation, software installation, wiring guides, and sample code, enabling users to successfully record and save voice files using Arduino.

    2. Example Code for Arduino-Playing

    Power on the module then it enters the music mode. Start playing the previously-recorded file, pause 3s later, play the next song 3s later, play the last song 3s later, and play the file of specific number(FILE0000) once 3s later.

    FAQ

    • Very nice product !

      Hi Demon,

      Thanks for your valuable feedback.
      The reason for the slow copying of files is that the hardware only supports upto that limit, so fast that it cannot be solved.
      Regarding, file naming and random playback problems, since our definition of this module is a recording and playback module, not a music playback module.

      In addition, we will launch a new music player module in March

    • If you find that your module cannot record sound properly

      If you find that your module cannot record sound properly, please update the firmware by the following steps:

      Unzip the download.zip

      Enter the folder download/download to find the file download_flash_sdk.bat

      Connect your module to the PC via a USB cable that can transfer data, double click download_flash_sdk.bat to burn the firmware.
