DFplayer and Arduino

Account cancelled 2018-04-21 15:40:42 3073 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); } }
