ฝากเนื้อฝากตัวด้วยนะครับ   คือผมได้โหลด library MPU6050 มาครับ นำไปใส่ใน library แล้ว แต่เมื่อผมทำการ test MPU6050_raw
แต่เมื่อ verify แล้ว ERROR แสดง MPU6050 does not name a type 
ผมจะแก้ไขปัญหาอย่างไรครับ   ขอบคุณครับ

// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files
// for both classes must be in the include path of your project
#include "I2Cdev.h"
#include "MPU6050.h"

// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation
// is used in I2Cdev.h
#if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE
    #include "Wire.h"
#endif

// class default I2C address is 0x68
// specific I2C addresses may be passed as a parameter here
// AD0 low = 0x68 (default for InvenSense evaluation board)
// AD0 high = 0x69
MPU6050 accelgyro;error บรรทัดนี้ครับ
//MPU6050 accelgyro(0x69); // <-- use for AD0 high

// uncomment "OUTPUT_READABLE_ACCELGYRO" if you want to see a tab-separated
// list of the accel X/Y/Z and then gyro X/Y/Z values in decimal. Easy to read,
// not so easy to parse, and slow(er) over UART.
#define OUTPUT_READABLE_ACCELGYRO

// uncomment "OUTPUT_BINARY_ACCELGYRO" to send all 6 axes of data as 16-bit
// binary, one right after the other. This is very fast (as fast as possible

รบกวนพี่ๆช่วยแนะนำด้วยครับ  ขอบคุณครับ
