MPU6050 (Digital Accelerometer & Gyro)¶

The MPU6050 is a serious piece of motion-tracking technology. It combines a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor (DMP).

Why use MPU6050?¶

• Digital Interface: Uses I2C, allowing it to share the bus with other sensors like the DHT or LCD.
• High Precision: Provides 16-bit resolution for each axis.
• Integrated Gyroscope: In addition to vibration (acceleration), it can measure rotational movement and orientation.

Code Example¶

#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>
#include <Wire.h>

Adafruit_MPU6050 mpu;

void setup() {
  Serial.begin(115200);
  if (!mpu.begin()) {
    Serial.println("Failed to find MPU6050 chip");
    while (1) { delay(10); }
  }
}

void loop() {
  sensors_event_t a, g, temp;
  mpu.getEvent(&a, &g, &temp);

  Serial.print("Accel X: "); Serial.print(a.acceleration.x);
  Serial.print(" m/s^2, Y: "); Serial.print(a.acceleration.y);
  Serial.print(" m/s^2, Z: "); Serial.print(a.acceleration.z);
  Serial.println(" m/s^2");

  delay(500);
}
