This project was undertaken as a final-year initiative aimed at addressingthe serious issue of accidents and damage caused by drunk driving. The system was designed around an Arduino Uno3 microcontroller connected to an alcohol detection sensor, which analyzes the driver’s breath. If alcohol is detected, the vehicle’s engine is automatically shut down, and an emergency siren is activated to warn others and prevent potential hazards. The alcohol sensor is strategically mounted on the steering wheel so that any excessive presence of alcohol beyond a 
set threshold disables the ignition system. The Arduino continuously monitors data from the sensor and activates a locking mechanism that prevents the engine from operating, thereby helping reduce the risk of accidents, injuries, and loss of property.

Mazkur loyiha bitiruv ishi sifatida amalga oshirilib, alkogol ta’siriostida transport vositasini boshqarishdan kelib chiqadigan yo‘l-transport hodisalari va zararni kamaytirishga qaratilgan. Tizim Arduino Uno3 mikrokontrolleri asosida ishlab chiqilgan bo‘lib, u haydovchi nafasidan namunani tahlil qiluvchi alkogol sensori bilan bog‘langan. Agar alkogol aniqlansa, avtomobil dvigateli avtomatik ravishda o‘chiriladi hamda atrofdagilarni ogohlantirish va xavfning oldini olish maqsadida favqulodda signal beriladi. Alkogol sensori rulga joylashtirilgan bo‘lib, belgilangan me’yordan yuqori darajada aniqlanganda, yondirish (зажигание) tizimi bloklanadi. Arduino sensor ma’lumotlarini uzluksiz nazorat qiladi va dvigatelni ishga tushirishga yo‘l qo‘ymaydigan blokirovka mexanizmini faollashtiradi. Bu esa avariya, jarohatlar va moddiy zararlar xavfini kamaytirishga xizmat qiladi.

Настоящий проект был выполнен в качестве выпускной работы и направлен на решение серьёзной проблемы дорожно-транспортных происшествий и ущерба, вызванных управлением транспортными 
средствами в состоянии алкогольного опьянения. Система разработана на основе микроконтроллера Arduino Uno3, подключённого к датчику определения алкоголя, анализирующему дыхание водителя. При обнаружении алкоголя двигатель автомобиля автоматически отключается, а также активируется аварийная сирена для предупреждения окружающих и предотвращения возможной опасности. Датчик алкоголя стратегически установлен на рулевом колесе, что позволяет при превышении установленного порогового уровня блокировать систему зажигания. Arduino в непрерывном режиме контролирует данные с датчика и активирует блокирующий механизм, препятствующий запуску двигателя, что способствует снижению риска аварий, травм и материального ущерба.
