Скачать или смотреть DIY Drunk Driving Prevention System: Alcohol Sensor Project

Welcome to the official build video for the Robowunder Drunk Driving Prevention System!

In this comprehensive, step-by-step DIY project, we demonstrate how to create a vital safety feature using a gas sensor and a popular microcontroller.

This is an essential hands-on project for students, hobbyists, or anyone wanting to learn about advanced sensor interfacing, safety protocols, and embedded system design.

We cover the entire circuit diagram, components needed (MQ-3 Alcohol Sensor, Microcontroller, Relay, Display), and the programming logic that reads the sensor's alcohol level, compares it to a safe threshold, and activates a relay to prevent the vehicle's ignition from starting.

This robust STEM project is ideal for educational use, vehicle security research, or simply mastering sensor calibration.

The Robowunder Drunk Driving Prevention System is a high-impact, rewarding build focused on road safety!

What You'll Learn in This Video:

✅ Chemical Sensor Interfacing: Accurately reading and interpreting data from the MQ-3 Alcohol Gas Sensor.

✅ Safety Programming Logic: Writing code (e.g., in Arduino IDE) to implement conditional lock-out based on a specific alcohol threshold.

✅ Actuator Control: Safely connecting and controlling a Relay to simulate locking or disabling a vehicle function (like the ignition).

✅ Real-World Impact: Creating a functional prototype for a critical system that promotes road safety and prevents accidents.

This project is a fantastic introduction to embedded systems for public safety and provides a deep understanding of how sensors and programming can enforce safety regulations.

It's a critical, high-value build for future engineers!

It's a fun and challenging build that will level up your game nights!
