🧭 3-Axis Gyroscope & Accelerometer Measurement using MPU6050 and Arduino

This project demonstrates how to interface an MPU6050 6-axis motion sensor (3-axis accelerometer + 3-axis gyroscope) with an Arduino using I²C communication. The sensor data is read, decoded, and printed to the Serial Monitor in a structured, human-readable format.

📊 Output Format

The output in the Serial Monitor looks like this:

X-Axis Acceleration: -245, Y-Axis Acceleration: 16384, Z-Axis Acceleration: 512,
X-Axis Gyroscope: 0, Y-Axis Gyroscope: 200, Z-Axis Gyroscope: -87

📐 Why the Output Values Make Sense

The MPU6050 outputs data in signed 16-bit format, where:

• The raw output range is from -32768 to +32767
• At ±2g accelerometer scale:
  • 1g ≈ 16384
  • 2g ≈ 32768 (maximum value)

So in the GIF, if you see an acceleration value close to ±16384, it indicates approximately ±1g — consistent with gravity when the sensor is still or tilted. Similarly, gyroscope values reflect angular velocity in raw counts that correspond to °/s after scaling.

Formula used for scaling:

g_force = raw_accel_value / 16384.0;
deg_per_sec = raw_gyro_value / 131.0;
