Annotation: The free fall acceleration of an object on Earth is a crucial physical parameter used in various scientific and engineering applications. Measuring this acceleration can be achieved using an accelerometer, which measures acceleration in one or more axes. The ADXL345 accelerometer is a popular choice for such measurements due to its high accuracy, wide measurement range, and ease of interfacing with microcontrollers. The ADXL345 accelerometer is a popular choice due to its accuracy, range, and easy interface with microcontrollers. This lab explores determining the free fall acceleration of Earth with the ADXL345 accelerometer, an Arduino board, and software. Raw acceleration data is read and the magnitude of acceleration is calculated using the Euclidean distance formula. Data can be viewed graphically with programs like Arduino IDE, Processing, MATLAB, or Python. The ADXL345 accelerometer and available visualization tools make this method effective and efficient for measuring Earth's free fall acceleration.
