Capture sensor events
GPIO interrupts allowed the system to respond to sensor transitions without relying only on continuous polling.
Collision Detection System
Accurate sensing depended on timing. GPIO interrupts and hardware timer capture made it possible to measure ultrasonic echo delay precisely.

Project overview
I developed a collision detection system using bump and ultrasonic sensors. The MSP432 measured distance through ultrasonic echo timing and detected physical impact through bump-sensor input.
Engineering approach
From idea to working system.
Measure echo delay
I used hardware timer capture to record ultrasonic echo timing precisely enough to support distance measurement.
Combine detection modes
Ultrasonic sensing provided distance awareness while bump sensors provided direct impact detection, giving the system two complementary inputs.
