i really like this type of project so i would to know whether is possible to connect the motor and the display that will demonstrate immediately when the alcohol is detected
Thanks very much for this video, i want to ask you is it possible to display the concentration in ppm versus Time in excel using this sensor
thanku
Hi man when i put alcohol near it it buzz for like 1 minute than it turns off what could be problem i see when you put it buzz when you remove it it turns off i dont know???
hello, does it also works on arduino uno R3 CH340
Through 180ohm resistor can be replace another
how i can reverse the output, i want that led and buzzer should on when it dosent sense alchohol but after sensing alchohol it should stop buzzing and led should off …..plzz help
Can you please tell, me which software do you use for making circuits online?
Fritzing
Hello sir good evening. Sir can it sense alcohol present in santizers. Or we have to use real alcohol ???
Code properly compiled , but it didn't sensed the alcohol of sanitizer
Please how to connect a motor with this
Can we use face and voice recognition in arduino along with alcohol sensor?
so that on detecting alcohal we take picture of drunk person and send it to their family members.
Code is correct
How get the source code
Did you got the code bro...
Bro in this experiment how we can connect lcd display 16x2 please reply bro
lmao what a savage. He heart reacted to you but ignored your desperate cries for help.
how can you calibrate MQ3 sensor?
Hello does this work with any a mb-102 breadboard?
Yes it will
Which app should i use for coding
Arduino IDE
Hello sir it is not excuted
Can we use mq4 sensor
Yes
Sir can send report of this project
Bro code
can i use 9V battery or any batteries than can power it?
Yes
@@sritu_hobbywhat OHM can i use other than 180 ohm resistor?
Sir , in which language the code is written ?
Thanks sir
will this code run in arduino Uno ATmega328P?
Yes of course
@@sritu_hobby thanx
Bro it's showing com3 port not com4 is it will work on that port?
A mí tampoco me aparece com4 solo com3
From where power is provided to circuit
The cable is providing the required voltage, it is connected to some voltage source
Sir i want to do this project can u send me the code and pin diagram Please
Please visit the video description
Sir I also want to do this project plz send me programing in this project by uno
Bro please
Sir I want to ask question related this
@@sritu_hobby I have made this project
But in that light is not getting on( no problem in light)
What I do?
@@sritu_hobby all are correct
I joined just you did
Mq3 sensor without sensing Alcohol buzzer start beeping
@@628adarshmishra8 i am facing the same problem..were u able to resolve this?
Faving problem in uploading
Can u explain why I am getting uploading problem it shows uploading problem message error please help me with it
What's the issue?
WHERE IS THE LINK BRO?

Replace arduino board
Please giveaway mq3 to me
Give me project code

i want code sir
Description
Code bro
Description
Followed the tutorial for 3hrs still not working😢
worked bro??
Source code please
Description
sir after sensing alcohol it continous to beep for 1 or 2 minute i want to reduce its beeping duration
plz tell me changes i need to do in code
plz sir i will be very thankful to you plz sir plz
Check this code
i want the source code
Description
Sir can we connect a motor with this please help
You can connect it
Bro I just take a Bo motor and connect it with two battery and relay and just connect to the breadboard boom it start working and when it beeps the motor stops
Can you give coding link
