DF Player Mini (Trying to add sound to code)

Using Arduino Audio
1

I can't see my error here. This code is pretty long but what I'm concerned with it the state machine TorpSequence. When it reaches case FLASHON, the file never triggers to play. I know its wired correctly because it will play with the example code it came with. (Again, I am not a programmer but please can someone show me what I did wrong here? Code might not post, 9k limit)

Yeah I couldn't post the code but the .ino is attached. I'm concerned with State Machine Torp Sequence. The RX and TX pins are defined but...I'm doing something wrong in this code.

FINAL_V3.0.ino (12.2 KB)

You're using a depricated library for the DFPlayer, you should use this one instead (installable via the Arduino IDE's Libraries Manager).

Other than that, I do see "case TORPSEQUENCE" doesn't have any way to escape and change state. I imagine that's another source of error in the code.

I will update my library. I tried moving the play command down to button states for button one after I posted but it failed to play.

Please post your new code in tags

I can't, it exceeds the 9k limit

Ok, then post your new code as an attachment. A wiring diagram would also be useful.

At this point it doesn't matter, I managed to get it to work but I'm disappointed I used delays. I inserted it into ENDSTATE of the stateMachineTorp(). Of course using delay pauses things so its not ideal but I need to define something like Mp3Millis or something. I'm just elated it works to a degree.

case ENDSTATE:
      {
        //wait here for 1 seconds
        if (currentMillis - fadeMillis >= 100ul)
        {
   
          analogWrite(led1, 0);
                   myMP3.play(1);
       delay (1000);
       myMP3.sleep();

          //we are now finished with this animation
          mState1 = TORPSEQUENCE;
        }
      }

      break;

Redefined code working :smiley:

     case ENDSTATE:
      {
        //wait here for 1 seconds
        if (currentMillis - fadeMillis >= 100ul)
        {

          analogWrite(led1, 0);

          myMP3.play(1);
          if (currentMillis >= mp3Millis + period1) {

            mp3Millis = currentMillis;
          }
          //we ar now finished with this animation
          mState1 = TORPSEQUENCE;
        }
      }

      break;
