Hi everyone, I am trying to get the DFRobot Mini MP3 player to work on an Arduino mega. Wiring : Mega MiniPlayer VCC(5v) (VCC) TX(18) (RX) RX(19) (TX) GND (GND) Mini Player Speaker SPK1 SPK1 SPK2 SPK2 Code: #include "Arduino.h" #include "SoftwareSerial.h" #include "DFRobotDFPlayerMini.h" DFRobotDFPlayerMini myDFPlayer; void setup() { Serial1.begin(9600); Serial.begin(9600); Serial.println(); Serial.println(F("DFRobot DFPlayer Mini Demo")); Serial.println(F("Initializing DFPlayer ... (May take 3~5 seconds)")); if (!myDFPlayer.begin(Serial1)) { //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){ delay(0); // Code to compatible with ESP8266 watch dog. } } Serial.println(F("DFPlayer Mini online.")); myDFPlayer.volume(10); //Set volume value. From 0 to 30 myDFPlayer.play(1); //Play the first mp3 } [WhatsApp Image 2023-07-06 at 12.00.58] [WhatsApp Image 2023-07-06 at 12.01.05] [WhatsApp Image 2023-07-06 at 12.01.06] I have tried with an without the 1K resistor on the Rx wire.
