Puzzle Lock System For Vehicle Safety

The abstract of this project proposes the Puzzle Lock System, which is specifically intended to avoid occurrences involving inebriated driving. An Arduino microcontroller is included into the system together with an LCD display, servo motor, buzzer, alcohol sensor, and shuffling number pad. The main goal is to develop a reliable system that needs customers to utilize the number pad to solve a randomly generated puzzle before turning on the car. An alcohol sensor confirms the driver’s sobriety at the same time. With the help of the LCD display, the user interface gives feedback on how well the problem is being solved as well as how much alcohol has been consumed. When impairment is detected, the servo motor physically blocks the ignition until the user solves the puzzle and reports sobriety, and the system sounds an immediate alert. This multifaceted strategy seeks to deter driving while intoxicated or impaired and to encourage prudent and secure vehicle operation.. To improve vehicle safety, this idea offers a complete Puzzle Lock System as a solution to the widespread problem of drunk driving. Modern technology is used in this system, which includes an LCD display, servo motor, buzzer, alcohol sensor, Arduino microcontroller, and a shuffling number pad. The main idea consists in giving drivers a mental challenge by using a randomly generated puzzle on the number pad. This novel method increases security by guaranteeing that only aware and concentrated people can start the vehicle. Concurrently, an alcohol sensor keeps an eye out for indicators of impairment in the driver’s breath, adding to the comprehensive safety system. The LCD display’s real- time feedback, which shows the measured alcohol levels and gives visual signals on how well the problem is being solved, enhances the user experience. The system sounds a buzzer alarm to notify users to possible dangers in the event of impairment. In addition, a servo motor is used as a physical barrier to prevent the ignition from starting until the driver completes the task and certifies sobriety. This multifaceted strategy seeks to encourage responsible driving practices while also preventing incidences involving inebriated drivers. The Puzzle Lock System is a proactive way to improve road safety and lower the dangers of driving while intoxicated or under the influence of other substances. It does this by incorporating cutting-edge technology.
