mpu6050

I have some problem.

I want to use “DFPlayer mini” through the value from MPU6050 gyro sensor.

but MPU6050 passing too many values at a time. (1111111111111122222222222222223333333…)

and the music from “DFPlayer mini” is under Buffering.

the music is very short (3~4 sec.)

and they communicate each other with xbee.

.

.

if (xbee.available()) {
char data = xbee.read();

if (data == ‘1’) {
Serial.print(1);
xbee.print(‘7’);

}else if (data == ‘2’) {
Serial.print(2);
xbee.print(‘8’);

} else if (data == ‘5’) {
Serial.print(5);
xbee.print(‘9’);
}
}

Are you looking to use angles 0 ~360° or do you want to use the raw rates of change the mpu6050 generates?

but MPU6050 passing too many values at a time. (1111111111111122222222222222223333333…)

The MPU6050 is NOT pushing data. Your code is pulling data.

and they communicate each other with xbee.

What does?

#include <SoftwareSerial.h>
SoftwareSerial xbee(2, 3);
#include <DFPlayer_Mini_Mp3.h>
SoftwareSerial mySerial(10, 11);

Only one instance of SoftwareSerial can work at a time. If you think you need more than one, you are using the wrong Arduino.
