Mar 28, 2024 · A "press and hold" on the "IO1" and "IO2" pins on the DFPlayerMini will increase and decrease the volume. A "short press" on those same pins are "NEXT/PREV" file.

Jan 11, 2020 · Hello, I am using a Arduino Mega 2560 and DFPlayer Mini to produce sound for my project, and was wandering, "Can I add a potentiometer to the Arduino to adjust the volume?"

Jul 19, 2024 · I'm also trying to have a volume knob by using a potentiometer by using pin A0. I'm having an issue where when I implement the code to control the volume, the buttons don't work anymore. Any help? Thank you! if (digitalRead(buttonPause) == ACTIVATED) if(isPlaying) pause(); isPlaying = false; }else. isPlaying = true; play();

The two buttons shown in the circuit above are used to change the music tracks and control the volume of the sound. The button connected to pin IO1 is used to go to the previous track and reduce the volume.

30 levels of volume adjustable, 10 levels EQ adjustable. The goal of this tutorial is to demonstrate the use of this module with Arduino, using the push buttons to instruct the Arduino to send serial commands to the module and control mp3. We will use three buttons to achieve this.

May 9, 2019 · I'm working on a project that utilizes a DFPlayer (detailed found here ) with an Arduino Mega. My project (schematic attached) is a combination of mp3 playback activated by capacitive touch buttons as well as a clock feature.

Feb 15, 2022 · Connect the 4 push buttons to the pin 2, 3, 4 of the Arduino for controlling the volume/start/stop and then connect the pin Rx and Tx pin of the DFplayer to Arduino pin 10 and 11.

May 4, 2018 · Master the DFPlayer Mini with this handy cheat sheet. Learn about its features, commands, and how to integrate it into your next project.

May 8, 2019 · I understand the DFPlayer has 2 pins for volume control (IO1 and IO2) that uses button presses to increase or decrease the volume. Currently I have the DFPlayer connected to a Arduino mega, and I am controlling the volume by code.

Mar 17, 2025 · In this guide, we explored how to interface DFPlayer Mini with Arduino, wire it properly, and control playback using code. You can extend this project by adding buttons, sensors, or Bluetooth control for a smart audio system.
