Drunk and Drive Detector With Arduino | Arduino Alcohol Detector with MQ-3 Sensor
DIY Alcohol Breathalyzer Tutorial

Description:
Welcome to our DIY tutorial on creating an Alcohol Detector using an Arduino Uno and an MQ-3 sensor! In this video, we'll guide you through all the steps necessary to build your own alcohol breathalyzer device. Whether you're a curious tinkerer or concerned about responsible drinking, this project is both informative and fun.

Resources:
We provide a comprehensive list of all the components you'll need for this project. You can easily find these items online or at your local electronics store. Additionally, we share links to download the necessary Arduino IDE and libraries to help you get started.

Connections Diagram:
Our video includes a detailed connections diagram that makes it easy for beginners to understand how to wire up the Arduino Uno, MQ-3 sensor, buzzer, and RGB LED. We'll ensure you get the wiring right the first time, saving you valuable troubleshooting time.

Code Walkthrough:
We walk you through the code step by step, explaining how it works and what each line does. Our code is designed to read the analog signal from the MQ-3 sensor, set a 350 ppm alcohol concentration threshold, and trigger different responses based on the alcohol level detected. If the alcohol concentration is above 350 ppm, the red LED and buzzer activate; otherwise, the green LED lights up, and the buzzer remains silent.

Demo:
We demonstrate the alcohol detector in action, simulating alcohol vapor near the MQ-3 sensor to show you how it responds to different concentrations. You'll see the red LED and buzzer activate when alcohol is detected and the green LED when the air is alcohol-free.

This video provides a detailed, step-by-step guide to help you create your own alcohol detector with an Arduino Uno and an MQ-3 sensor. Whether you're looking to learn more about sensor technology or build a practical device, this tutorial has you covered.
