The ObjecTrack Timer is a distraction-reduction countdown system designed to help users stay focused during study sessions or work periods. Its core purpose is to encourage users to set aside their phones or other distracting items by starting a countdown when an object is placed on the device. If the object is removed before the timer ends, the countdown simply pauses and resumes once the object is returned. An audible buzzer activates only when the timer fully completes. This system is powered by an Arduino Leonardo and uses a VL53L0X time-of-flight sensor to detect object presence. Countdown progress is clearly displayed on a MAX7219 LED matrix, providing a highly visible, dynamic readout of remaining time. The system is powered by a 9V battery, allowing for simple, portable use. Notable accomplishments include successful sensor integration, real-time display management, and building a hands-free timing interface. Future improvements may include rechargeable battery support, adjustable brightness, and wireless configuration options.
