Learn how to approximate pitch and roll using a 3-axis accelerometer in this comprehensive tutorial video. Explore a simple demo project that yields reasonable results for angles under 45 degrees, with the caveat that vibrations may be misinterpreted as tilt. Gain hands-on experience with the Adafruit BNO055 IMU Sensor and Arduino Nano for creating a portable system. Follow along as the instructor guides you through code implementation, calibration techniques, and troubleshooting common issues. Discover practical applications and limitations of this tilt determination method in Arduino-based projects.
