Great video.. but, how to print track title being played?
Assuming I've 200 tracks in the drive, how can I jump (in short step) playing track from 50th to 150th?

[@ravipandey-ut8wh]

why pin 4 is not defined in the code and why pin 9 is defined which is not in use, please clarify as I am new to dfplayer

[@hilmanalhadied361]

Usb A for input power or play from ufd sir??

[@muhammadbasir83]

How fast (in milisecond) this module can respond to play the selected file..???. Thank you

[@jcelectrotorial9603]

new subscriber here. just asking if you have code for arduino and dfPlayer will play the song at every 1 hour

[@furkancanoz6325]

Why did we connect DFplayer rx and tx pins to d12 and d11 pins, not rx-tx pins on arduino?

[@AnasKuzechie]

You could, the serial software library needs any 2 digital pins.

Sir if i wanted to add an internal power source what should be it's specifications

[@AnasKuzechie]

Hello. The whole circuit in this project is powered by supply from the Arduino. When you suggest internal power source, do you mean an external power supply?

[@bhargavaithal]

@@AnasKuzechie yes sir like a battery. i wanted to do a casing and hence the word internal was used.
