DFPlayer Mini with analog volume control
Account cancelled 2019-05-08 08:20:32 3137 Views1 Replies Hoping for a little help or suggestions. I'm working on a Alarm clock/MP3 player. My project is working great, however I want to control the volume on the user interface. 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. I would prefer to use a potentiometer other than using the push buttons. Can this be done using the DFPlayer. I have read through the datasheet and the dfrobot website and still a bit uncertain if I can make this work without adding in an additional amplifier module that has a build in potentiometer.
I would appreciate any helpful feedback or suggestions.

I dont think it can controll the volume by poteniometer, the potentiometer output analog is not suitable because it is graded to output. techsupport
