MPU6050 gives the same values every time

[vanjo9800]

Hello,

 

I use the MPU6050 with an ESP8266. I have connected it to VCC, Ground, SDA, SCL of the ESP8266. When I power the board for an amount of time the MPU6050 works perfectly. However, after some moment it returns the same values no matter moving it. I first thought it was the buffer and tried emptying it at a specific amount of time. However, this made the problem appear sooner than before. After a restart of the ESP9266 board, the MPU6050 works fine again.

 

This is the code which I use to obtain the values from it:

    in setup:

    const int MPU_addr=0x68;
    Wire.begin();
    Wire.beginTransmission(MPU_addr);
    Wire.write(0x6B);
    Wire.write(0);
    Wire.endTransmission(true);
    delay(10);
    
    in loop:

    Wire.beginTransmission(MPU_addr);
    Wire.write(0x3B);
    Wire.endTransmission(false);
    Wire.requestFrom(MPU_addr,14,true);
    AcX=Wire.read()<<8|Wire.read();
    AcY=Wire.read()<<8|Wire.read();
    AcZ=Wire.read()<<8|Wire.read();
    Tmp=Wire.read()<<8|Wire.read();
    GyX=Wire.read()<<8|Wire.read();
    GyY=Wire.read()<<8|Wire.read();
    GyZ=Wire.read()<<8|Wire.read();
    //Applying a formula to turn raw values into Yaw, Pitch and Roll
    int16_t roll=atan2(AcY,AcZ)*180/PI;
    int16_t pitch=atan2(AcX,sqrt(AcY*AcY+AcZ*AcZ))*180/PI;

If the values that repeat are important, I can provide them. They are the same every time.

 

What am I doing wrong?

 

Thank you in advance!!!

The problem was that the wires were not soldered properly. I resoldered them and now everything works fine !!!

I hope you reply pls pls pls

I am making similar projects using Arduino mini pro and mpu6050 and it's giving same value everytime I've tried every single thing but I remember from your post that I also haven't soldered them rather I have used breadboard instead will it work fine if I solder it ?  Your reply will be help full i have to submit this project in a week
