Alcohol detection and engine locking system using Arduino Uno and MQ3 sensor. 

Bro this code is correct

A suggestion from my side. Please mention pin numbers while you make schematics. It would be helpful for us to understand the connections better. Anyways it's good to see nowadays teens are exploring new technologies.

@Hike Tech sir is that code full or half why because iam goona do this project in my college so plz reply this 😊

@Hike Tech sir is that code full or half why because iam goona do this project in my college so plz reply this 😊

Please Explain about The Bread Board Connection in project More🙏🙏

Can u give me the documentation of this project plz sir

I want full bro I should submit it by tomorrow

Sir please replay my question my question is kay ye code uplode karne ke baad 100% kam karega kay ye project work kare ga kay

Is there any need for transistor and relay? Can I make this project without relay and transistor? Will it work? Please upload a video making alcohol detector with automatic engine lock without transistor and relay.

Bro is the circuit diagram proper. My buzzer and led is turning on but the motor isn't working

Can i uplode this code and make 5his wothou relay module plzz tel tomorrow is subnimiton plzz tell

👏👏👏 congratulations 🎉 you did it bro🔥🔥

@Hike Tech sir how can i get this code, want to do this project Please suggest

@Hike Tech sir is that code full or half why because iam goona do this project in my college so plz reply this 😊

Battery is series connect?

Sir following your circuit my Alcohol Sensor is not sensing alcohol

what if driver drinks while driving the vehicle ,which means he/she is not drunk while starting the car but in the middle of driving they drinks does it stop wherever it is or wat will happen

Can you explain the connection

Could you please provide the link of that Arduino Uno?

Where you from I want to meet you

Code bro ??

@Hike Tech sir is that code full or half why because iam goona do this project in my college so plz reply this 😊

iťs not working waste of seeing this video

Does this work in tinkercaed

This should be put on every cars to reduce accidents related to drunk driving

which type of transister you use??

How can we do LCD interfacing to see level of alcohol consumption??

bro i did it on ardiuno deumilanove......does it work

Sir is the diagram correct?

According the circuit diagram, this project will works or not

Instead of connecting switch can I connect push button

Sir is the diagram correct?

Which type of relay you used

Bro can I get the code for this project..... Opening the link in description it's showing not having access to file Can I contact you regarding this ??

How those two batteries are connected can u explain plz

Can 4class student do it

Cost of this project

Hello soham here .. will suggest home automation as well

This is a very good

Can I have you email. I need you to make a project for me

Not run

Bro can u clarify Relay connections? , i'm little confused

This code alone is not enough brother

Hi sir can u help me in project

Greatttt!

Very good (khud mat kr liyo😆)

Amazing content!!! Keep it up🤗🤗🤗

Bro we want to do this circuit for my project work will give send the components and aurdino with programming coded

Very nice but can you please tell that on which software had you made this circuit

😍😍🔥🔥

Nice bro 😁

Amazing one 👍 need a full code
