Hover a pin or a wire to trace the connection.

Code

mpu6050.ino
// Print acceleration (m/s^2) from an MPU6050 over I2C.
// Install "Adafruit MPU6050" + "Adafruit Unified Sensor".
#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>
#include <Wire.h>

Adafruit_MPU6050 mpu;

void setup() {
  Serial.begin(9600);
  if (!mpu.begin()) {
    Serial.println("MPU6050 not found");
    while (1);
  }
}

void loop() {
  sensors_event_t a, g, temp;
  mpu.getEvent(&a, &g, &temp);
  Serial.print("Accel X:"); Serial.print(a.acceleration.x);
  Serial.print(" Y:"); Serial.print(a.acceleration.y);
  Serial.print(" Z:"); Serial.println(a.acceleration.z);
  delay(300);
}

Steps

  1. Install "Adafruit MPU6050" and "Adafruit Unified Sensor".
  2. Wire: VCC to 5V, GND to GND, SDA to A4, SCL to A5.
  3. Upload and open the Serial Monitor — tilt the board and watch the axes change.
