mpu6050

Using Arduino Programming Questions
#1

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?

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.
