How to wire a DFPlayer Pro to play audio immediately it is powered

I would like to wire my DFPlayer Pro so that as soon as it receives power it starts to play the audio file it has - ie without pressing the button on the device. It should play the audio file on loop.

Is there a way to do that?

Hi，You don't need any wiring for this — the DFPlayer Pro auto-plays on power-on by default: "When powering on, the module enters music mode and starts playing audio files." For looping, set AT+PLAYMODE=2 (repeat all) over UART. https://wiki.dfrobot.com/dfr0768/docs/20423
