DFplayer and Arduino
Account cancelled 2018-04-21 15:40:42 3019 Views0 Replies I'm trying to have a file play with the press of a momentary button. (I am using the DFRobotDFPlayerMini library with an Arduino) If I let off the button the file stops playing. If I don't use an arduino, the file will play once via the IO pins but I would like to get this function on the arduino through serial trigger. The code I am using is below.
Code: Select all
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
int buttonInput = 3;
int buttonState = 0;
SoftwareSerial mySoftwareSerial(10, 11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
void printDetail(uint8_t type, int value);
void setup()
{
mySoftwareSerial.begin(9600);
Serial.begin(115200);
pinMode(buttonInput, INPUT_PULLUP);
Serial.println();
Serial.println(F("DFRobot DFPlayer Mini Demo"));
Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)"));
if (!myDFPlayer.begin(mySoftwareSerial)) { //Use softwareSerial to communicate with mp3.
Serial.println(F("Unable to begin:"));
Serial.println(F("1.Please recheck the connection!"));
Serial.println(F("2.Please insert the SD card!"));
while(true);
}
Serial.println(F("DFPlayer Mini online."));
myDFPlayer.volume(20); //Set volume value. From 0 to 30
}
void loop()
{
buttonState = digitalRead(buttonInput);
if (buttonState == HIGH) {
myDFPlayer.play(1);
}
}
