During two months on the Automation_Course_2025A repository, Rumelt developed four hardware-integrated features and performed key maintenance to streamline onboarding and future development. He built Arduino-based systems for distance sensing and interactive object detection, combining C++ with embedded systems skills to integrate buttons, LEDs, servos, buzzers, LCDs, and ultrasonic sensors. Rumelt also implemented a PID controller for motor positioning using encoder feedback and serial input for target angles, enabling precise hardware control. His work included thorough repository cleanup, removing obsolete files and standardizing structure, which improved maintainability and reduced technical debt. The contributions demonstrated depth in IoT and motor control.

January 2025 — Automation_Course_2025A: Delivered two hardware-focused features, completed repository cleanup, and strengthened maintainability to support rapid, scalable course content delivery. Key features delivered: - Arduino Group 15 Interactive Object Detection: new Arduino sketch with button, LED, servo, buzzer, ultrasonic distance sensor; reads button presses to control LED/servo; measures distance; triggers buzzer and LCD message when object is within 40 cm; servo moves to 180° when LED is on and detaches when LED is off. Commit: 0a9ce078ebc4b502b3d538bacc7ecaab315258e3. - PID Controller System for Motor Positioning (Encoder-based): Arduino sketches implementing PID control for motor position using encoder feedback; supports target angles via serial input; includes PID tuning and motor drive. Commits: 3b3e422f108c8420a409a377d9509c45dd3c0d40, 907ffb3e78cfe398eed1a5e616f2315294b9aade. Major bugs fixed/maintenance: - Repository Cleanup and Structural Maintenance: removal of obsolete files/directories and reorganization (deletion of EX3 Group_15 directory, removal of PDFs and PID files, creation/removal of GROUP_15 and GROUP15 folders, and placeholder files). Representative commits include a469e59eda6d9e0ea5423af925229b78a56ed237, 99665ee1e9c387d6af64378973a80748c9297124, f4e1ee53b5b3acee06ab11e2066013562c5bd801, 216a87ad06bc9e30c832d63595c2526941d2e334, 0cb319c845a5c98ea9b875eb37eaf6ae5a78dbc4, 328f35959bdd0ce725b9013492a019b6b9b28972, 0b3fa7be40dd99a207d409e1e53c943c5156a320, b689da6b83d76ef749e24c3ad3e96f40a4db73b9, a0fbc0b8a5aeef26eef492fd3db3ae297e114040, 9fda03674a53343d3563d83fc05ad5aae5fc80a0, efff8125793c9a18b0494096ae0a6e8537224943, faf25dc9d86d3bcf8e65dd719b79b9e219c60b71. Overall impact and accomplishments: - End-to-end hardware-software demonstrations improved, course materials more reliable, and onboarding faster. - Reduced technical debt and prepared the project for future group expansions and feature scaling. Technologies/skills demonstrated: - Arduino programming and hardware integration (button/LED/servo/buzzer/LCD, ultrasonic sensing) - Encoder-based PID control and serial I/O for remote target setting - Hardware-software integration, testing, and validation - Software hygiene and repo structure maintenance (folder standardization, obsolete-file cleanup, clear commit history).
