Lesson 49: Improving IMU Performance with a Complimentary Filter

This tutorial covers improving tilt measurement accuracy using the MPU6050 sensor and Raspberry Pi Pico W:

• Setup: Connect the MPU6050 to the Raspberry Pi Pico W.

• Challenges: Accelerometers are noisy; gyroscopes suffer from drift.

• Solution: Use a complementary filter to combine accelerometer and gyroscope data.

• Implementation: Calculate roll and pitch, blend using a complementary filter for accuracy and low noise.

• Results: Achieve accurate, responsive tilt measurements with minimal noise and drift.

• Homework: Implement and fine-tune the method, exploring ways to eliminate steady-state error.
