mpu6050 arduino uno stoping after a few seconds - arduino

Question

I was trying to use MPU6050 and a servo motor. but mpu6050 arduino crashing after a few seconds .
i used arduino uno and sg90 servo motor.
this is my code.
#include "Wire.h"
#include <MPU6050_light.h>
#include <Servo.h>
Servo myservo;
MPU6050 mpu(Wire);
unsigned long timer = 0;
int pos = 0;
void setup() {
myservo.attach(10);
Serial.begin(115200);
Wire.begin();
byte status = mpu.begin();
Serial.print(F("MPU6050 status: "));
Serial.println(status);
while(status!=0){ } // stop everything if could not connect to MPU6050
Serial.println(F("Calculating offsets, do not move MPU6050"));
delay(1000);
// mpu.upsideDownMounting = true; // uncomment this line if the MPU6050 is mounted upside-down
mpu.calcOffsets(); // gyro and accelero
Serial.println("Done!\n");
}
void loop() {
mpu.update();
//Serial.println(mpu.getAngleX());
int lastan = (mpu.getAngleX()-70)*-1;
if ((lastan> 0) || (lastan< 180)){
myservo.write(lastan);
timer = millis();
}
}

Answer 1

From my view you have to check following line again:
if ((lastan> 0) || (lastan< 180))
Its always true because when lastan is less than 0 its also less than 180. Same applies to lastlan bigger than 180... Then first argument is true.
I assume you need to change this line to:
if ((lastan> 0) && (lastan< 180))
