Playing specific audio with push buttons using just a DF player

Using just a DF player, you can play specific audio file with specific push button. You can see the full schematic chart in below link. Basically DF player will recognize commands by the difference in electric current, hence why the difference in resister ohm in Adkey1 and Adkey2. I’m using this to add sound effect for my model train station.

Great! Perfect for general station announcements (not ads!)

Hey thanks! Simple and easy

[@Rayyan-mo8gv]

Hi, how do I determine the resistor configurations? (Urgent please!)

[@Rayyan-mo8gv]

and what type of resistors are you using as well? thank you!

[@user-tu8fg7gm7g]

do we need to upload the code?

[@jonicurn100]

Awesome! How did you do this without code?

[@fabiozuccoli5802]

yeah, im wondering the same thing
