Project Details

keyRING - Smart Key Holder

As part of the keyRING project, I designed a system that senses keys using a spring-like mechanical switch and a sonar sensor to detect door movement. I programmed the ATmega328P in C to communicate with the switch for key detection using interrupts. This cost-effective design earned the "Cheapest Hardware Hack" award while achieving all project goals.
