Importance and Utility of MPU-6050

The MPU-6050 is a popular and versatile motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer in a single package. It is widely used in various applications such as robotics, drones, virtual reality, and motion sensing devices. The MPU-6050 provides accurate and reliable motion tracking data, making it an essential component for many electronic projects.

Project: Building a Self-Balancing Robot Using MPU-6050

In this project, we will use the MPU-6050 to create a self-balancing robot. The objective of the project is to design a robot that can maintain its balance on two wheels using the data from the MPU-6050. The robot will continuously monitor its tilt angle and adjust the motor speed accordingly to stay upright.

List of Components:

• Jumper Wires - Link
• Breadboard (1x) - Link

Examples:

Example 1: Initializing the MPU-6050

#include <Wire.h>
#include <MPU6050.h>

MPU6050 mpu;

void setup() {
  Wire.begin();
  mpu.initialize();

  // Optional: Set gyroscope sensitivity
  mpu.setFullScaleGyroRange(MPU6050_GYRO_FS_250);

  // Optional: Set accelerometer sensitivity
  mpu.setFullScaleAccelRange(MPU6050_ACCEL_FS_2);
}

void loop() {
  // Read sensor data
  mpu.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

  // Process and use the data
  // ...
}

Example 2: Calculating Tilt Angle

float getTiltAngle() {
  int16_t ax, ay, az;
  mpu.getAcceleration(&ax, &ay, &az);

  float tiltAngleX = atan2(ay, az) * RAD_TO_DEG;
  float tiltAngleY = atan2(ax, az) * RAD_TO_DEG;

  return tiltAngleX;
}

Example 3: Controlling Motors Based on Tilt Angle

void controlMotors(float tiltAngle) {
  float targetAngle = 0.0; // Desired tilt angle (e.g., 0 degrees)
  float error = targetAngle - tiltAngle;

  // Adjust motor speeds based on the error
  // ...
}
