👏👏👏 congratulations 🎉 you did it bro🔥🔥

[@hiketech439]

Thank you 🙌

[@nehalutade3150]

Greatttt!

[@alpzepta]

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

[@sharmishtabhatt3036]

Amazing content!!! Keep it up🤗🤗🤗

[@hiketech439]

Thanks..

[@vincentkiprono9188]

Amazing one 👍 , give me a full code

[@arjungowdaifs4852]

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..

@@hiketech439 or can I use one battery

[@prathamesh8736]

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

[@kethamahidar436]

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

[@pavankalyanGugulothu]

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

[@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

[@simranpreetsingh729]

which type of transister you use??

[@nmeghana9092]

Which type of relay you used

[@advaithvarrier5607]

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

[@jiteshchawardol3388]

😍😍🔥🔥

According the circuit diagram, this project will works or not

[@suppu15]

Instead of connecting switch can I connect push button

[@NidhiKumari-vb9se]

Could you please provide the link of that Arduino Uno?

[@user-oe4qx6iq4m]

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

[@pratik0777]

Sir following your circuit my Alcohol Sensor is not sensing alcohol

[@sukeshnisalunkhe6289]

Can u give me the documentation of this project plz sir

[@vanamhemanth3723]

Can you explain the connection

[@funandlearnwithaniket457]

Can 4class student do it

[@surya-su1oc]

Bro this code is correct

[@VisheshSDGowda]

Yes

[@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 !!

[@jeyamala1970]

Sir is the diagram correct?

[@maxplanck5550]

Hello soham here .. will suggest home automation as well

[@hiketech439]

Will try to make it soon !

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

[@kattanirmaltej2300]

s me too bro

[@watchingchull]

Where you from I want to meet you

[@suppu15]

How those two batteries are connected can u explain plz

[@suppu15]

Or can I use one battery

[@padalanikhil841]

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