IMU Data to Motion: Tutorial for Translating Sensor Data into Real-World Movement
Explanations
1. Libraries: Wire.h: For I2C communication. SparkFunLSM6DSV16X.h: To interface with the LSM6DSV16X sensor via Qwiic. Servo.h: To control the servos.
2. Setup Function: Initializes serial communication for debugging. Initializes the IMU sensor and checks if it's detected. Attaches servos to their respective pins and sets initial positions.
3. Loop Function: Reads magnetometer data (x, y, z). Maps x and y positional values to servo angles. Constrains angles to valid ranges (for this, 15-165 and 35-135 degrees). Updates servo positions based on mapped angles. Includes a small delay for stability.
Testing and Calibration:
Upload the Sketch: Connect your Arduino to your computer and upload the sketch using the Arduino IDE.
Power the Servos: Ensure the servos are powered correctly with an external power supply. (Small servos with light lode might be able to get away with using power from teh board.)
Observe Movement: Tilt or move the IMU sensor and watch how the servos react. The servos should adjust their positions based on the x and y acceleration data from the sensor.
