Dear all,
I am facing the issue during one of my project, I tried to intefacing the Mini df player and HX711 at one time to the arduino uno but, its not working, when i check it by using serial monitor it stuck on one point which is after printing version of hx711.
i am going to upload the full code and serial monitor window. Please help to find the problem.
Here the full code :
// #include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
#include "HX711.h"
HX711 scale;
uint8_t dataPin = 6;
uint8_t clockPin = 7;
float weight =0;
SoftwareSerial mySoftwareSerial(10, 11); // RX, TX
DFRobotDFPlayerMini myDFPlayer;
void printDetail(uint8_t type, int value);
int output;
int button=4;

// -----------------------------------------------------------------------------------------------------------------------------------------------------------
Serial.println(__FILE__);
Serial.print("HX711_LIB_VERSION: ");
Serial.println(HX711_LIB_VERSION);
Serial.println();
scale.begin(dataPin, clockPin);
scale.set_scale(420.0983);
// reset the scale to zero = 0
scale.tare(20);
// -------------------------------------------------------------------------------------------------------------------------------------------------

Serial.println(F("Unable to begin:"));
Serial.println(F("1.Please recheck the connection!"));
Serial.println(F("2.Please insert the SD card!"));

}
}

Serial.println(weight);

}
}

}
