Our teams Wooden Custom Detection Timer is an embedded system designed to function as an interactive countdown timer that detects the presence of an object placed on the device and responds when that object is removed. The system allows users to select preset countdown durations such as 5 minutes or 10 minutes and displays the remaining time during operation. When the detected object is removed before the timer completes, the system immediately stops the countdown and triggers an audible alarm to alert the user. This type of system could be used for productivity tasks, object monitoring, or timing applications where interaction with a physical object is required. The design integrates several key technologies including an ESP32 microcontroller, a load-based weight sensor for object detection, pushbutton user inputs for manual control, a digital display for time visualization, and a piezoelectric buzzer for audible alerts. The ESP32 serves as the central controller that processes sensor input, tracks elapsed time, and generates the required output signals to other subsystems. Power for the system is provided through a regulated 5 V supply generated by a DC-DC voltage regulator from the battery input. One of the most notable accomplishments of the project was successfully integrating multiple hardware blocks into a cohesive embedded system that meets strict engineering requirements such as a ±1 second response accuracy and a buzzer tone of 440 Hz ±1 Hz. The primary challenges involved validating electrical interfaces between modules, ensuring reliable sensor detection, and coordinating firmware with hardware timing behavior. Future improvements could include improving sensor filtering, adding more advanced alarm patterns, and refining the mechanical enclosure design to enhance usability and durability.
