Lesson 45: Calculating Height from a Dropped Object in Freefall

This tutorial covers using the MPU6050 sensor with the Raspberry Pi Pico W to measure vertical distances:

  • Setup: Connect the MPU6050 and OLED 1306 to the Raspberry Pi Pico W, ensuring secure connections to reduce noise.

  • Concept: Measure vertical distance by calculating the time (T_drop) in freefall and use it to determine the height dropped.

  • Equation: Calculate height (H) with ( H = 16 times (T_{drop})^2 ), converting time from milliseconds to seconds.

  • Code Implementation: Set up libraries, measure Z-axis acceleration to detect 0G, start a timer during freefall, and display height and drop time on the OLED.

  • Practical Demonstration: Test by dropping the sensor from known heights and adjust for accuracy as needed.
