Referring to this link Mini MP3 Player Interfaced with Arduino
I would like to know what ADKEY1 and ADKEY2 really does, including their "derivatives" (segment 2 to 4, segment 6 to 14)?
- Does it mean that when I press any segment button, it will play the corresponding mp3 saved in the SDcard then automatically stops depending on the "delay" allocated?
- Will it really stop playing the particular mp3 and never play the next mp3?
It is because I would like to utilize the TimeAlarms schedules output, that is, I will use the voltage output of the LED output to a Relay circuit to "short" the a button of a segment of ADKEY (to play the specific mp3) I know that the best way is to just program, but I know more of utilizing electronic components than programming.
I'm trying to check the net for sample code that implements playing of specified mp3 files at a particular time, and not sequential (playing the next mp3), but I what I found is not yet substantial for me.
If anyone knows the code, I would appreciate it.
I already have a working RTC Alarm using TimeAlarm library, but now I want to integrate the DFplayer mini in it.
