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.

[@hiketech439]

Thanks for ur suggestion🤗 I will definitely work on it..

[@shashanknitnavre9154]

👏👏👏 congratulations 🎉 you did it bro🔥🔥

[@hiketech439]

Thank you 🙌

[@alpzepta]

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

[@user-kg4gx5wq2r]

This is a very good

[@zeongo123]

bro did you make it?

[@Thunder-_-gamer.23569]

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

[@pavankalyanGugulothu]

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

[@surya-su1oc]

Bro this code is correct

[@shivakumarvishesh]

Yes

[@kethamahidar436]

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

[@guttireddydharanireddy482]

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

[@m-26venugopalraos76]

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

[@advaithvarrier2K13]

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.

[@saiarvindg9258]

Does this work in tinkercaed

[@simranpreetsingh729]

which type of transister you use??

[@prathamesh8736]

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

[@sukeshnisalunkhe6289]

Can u give me the documentation of this project plz sir

[@pratik0777]

Sir following your circuit my Alcohol Sensor is not sensing alcohol

[@vanamhemanth3723]

Can you explain the connection

[@prathmeshexperiment]

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

[@hiketech439]

Yes bro it will definitely work !!

[@user-oe4qx6iq4m]

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

Which type of relay you used

[@NidhiKumari-vb9se]

Could you please provide the link of that Arduino Uno?

[@suppu15]

Instead of connecting switch can I connect push button
