Welcome to our latest DIY electronics project! In this video, we'll guide you through the process of creating your own alcohol detection system using the MQ-3 sensor and Arduino Uno. Whether you're a hobbyist, a student, or just curious about how alcohol sensors work, this project is for you.

With clear step-by-step instructions, we'll show you how to set up the MQ-3 sensor with the Arduino Uno board, explaining each component and connection along the way. Once assembled, we'll demonstrate how the sensor detects alcohol vapor in the air.

But the fun doesn't stop there! We'll take it a step further by programming the Arduino to trigger an LED indicator whenever alcohol is detected by the sensor. Watch as the LED lights up in response to alcohol vapors, creating a visual alert system that's both practical and educational.


Whether you're interested in the science behind alcohol detection or just want to impress your friends with your DIY skills, this project is sure to spark your curiosity. So grab your Arduino Uno and MQ-3 sensor, and let's get started on building your very own alcohol detection system!
