The first of its kind. It's a self-locking, timer-based, Arduino-controlled Stop Smoking Device. Simple and easy to create at home!

This project was done just for fun. It wasn't my intention to actually complete a fun silly project like this, but oh well... I like doing random weird things! :-)

EXPANDED TECHNICAL DETAILS

Behavioral Modification Automation

This assistive tool uses a combination of timing and psychological triggers to help users reduce their nicotine consumption.

• Smart Cigarette Case Control: The Arduino manages a physical locking mechanism on a custom 3D-printed case. The case remains locked for specific intervals (e.g., 2 hours) based on a decreasing schedule.
• Motivational Display: An OLED screen shows the number of cigarettes avoided and the time remaining until the next available dose, providing positive reinforcement.

Progress Logging

• SD Card Integration: Records the exact time of every access attempt to a .CSV file, allowing the user to visualize their habit patterns and track their progress over weeks and months.
