![]() ![]() They can be used as it or can be calibrated as per the requirement of the user. We can interface an LCD or an OLED to present the measurement. The values at that particular time are shown on the Serial monitor. Rotate the sensor module in three dimensions as you like. As soon as the Serial monitor is launched, the position and orientation is displayed like The MEMS Sensor module will take up the values. They read the values of the accelerometer, gyroscope, and magnetometer. The loop will read the IMU through readSensor(). The execution cycle enters the void loop block when the status of IMU is more than 0. As this is a forever condition because of the while(1) statement, the code will not go further unless the status value is greater than 0. If the status is less than 0 i.e no voltage is received then the Serial monitor will display the messages “IMU initialization unsuccessful”, “Check IMU wiring or try cycling power” and then prints the value stored in status. Next a variable “status” is declared that checks the status of the IMU object. If the Serial monitor does not launch and no values are displayed then the execution cycle halts and the code will be stopped. First, it initializes the Serial monitor at a baud rate of 11520 bps. The void setup block executes two conditions. an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0圆8 It is done with the help of the MPU9250 sensor to store and act on the data and return the respective measurements. #include "MPU9250.h" IMU ObjectĪn object “IMU” is created with an address i.e. Through these inbuilt codes, it will take in, process, and output the acceleration, angle, and magnetic field to determine the position and orientation of the module. It has already written codes for reading the values of the accelerometer, gyroscope, and magnetometer. Include the concerned header file, to interface the MPU9250 9-DOF MEMS Sensor Module to the Arduino. To program a code in Arduino, the first is always to add the header files. ![]() Serial.println(IMU.getTemperature_C(), 6) Serial.println("Check IMU wiring or try cycling power") Serial.println("IMU initialization unsuccessful") Now let’s see how to interface Arduino with MPU9250 module. Therefore, you can use any Arduino module. In this section, we will see how to use MPU9250 with Arduino.Īlmost all Arduino modules support at least one I2C communication port. MPU 9-DOF MEMS Sensor Module interfaces with any microcontroller using an I2C bus. This section deals with the interfacing of an Arduino microcontroller to the MPU 9-DOF MEMS Sensor Module. It is embedded with a Self-test function to diagnose the operations of the module to ensure its proper functioning.The module has I2C, SPI and an additional Auxiliary I2C interface. ![]()
