Across the Wall (Smart Basketball Trajectory & Shot Counter)
Source: Stemoto Original
Inspired by the Mumbai girls' basketball team (Nagpada Basketball Association). Build a mini basketball hoop with an IR break-beam sensor to count successful baskets, track shooting percentage, and calculate parabola trajectories.
