Summary

This circuit involves an Arduino UNO microcontroller interfaced with an MPU-6050 accelerometer and gyroscope sensor. The Arduino UNO reads data from the MPU-6050 and processes it to output the accelerometer readings on the serial monitor.

  data.Y = map(ay, -17000, 17000, 0, 255); 
  data.Z = map(az, -17000, 17000, 0, 255);  // Y axis data
  delay(500);
  Serial.print("Axis X = ");
  Serial.print(data.X);
  Serial.print("  ");

  Serial.println(data.Z);
}

This code initializes the MPU-6050 sensor and reads the accelerometer data in the loop. The data is then mapped to a range of 0 to 255 and printed to the serial monitor.
