Your are only the one who I can trust for project codes and making them
Could u give me the whole cod of this project?
Alhamulillah...dapet ilmu lagi, sukses selalu terimakish banyak Kami do'akan semoga sedekah ilmu program MQ2 ini berkah barokah pa Guru. Amiin YRA
Thanks
muy buena explicacion, podre usar un microcontrolador en vez del arduino? o que cosa cambiaria?
sir is it necessary to select only com 4
do we can select other com
do i have to use the same resistor or its ok to use another one
Can I replacy my buzzer somewhere else since the distance from positive and negative is big and my buzzer is small?
Great video
Glad you enjoyed it
do i have to use the same resistor or its ok to use another one
What is the use of the resistor used in this project?
Sir ye sirf lpg gas ko hi detect krta h kya ....and mera buzzer to work kr h but still light ad lcd is not working
Tooooop
Code not working why error in header file
Hello, Good day. I have connected it, but the code is giving me issue, at "lcd.init();" and the error message is this : 'class LiquidCrystal_I2C' has no member named 'init'
. Please i need help.🙏🙏🙏🙏🙏
Did he reply
What did you sort that problem out
Hlo,how to resolve it
please tell me something, the value that it reads on the LCD is ppm or what is it??? i mean what units do they read???

sir this error is showing noiw
avrdude: ser_open(): can't open device "\\.\COM4": Access is denied
Sir Buzzer always sound kar ta ha
I HAVE TO SUBMIT IT BY TOMORROW
SIR I HAVE FOLLOWED EACH STEP DONE EVERTHING MY LIGHT ARE ON BUT MY GAS SENSOR IS NOT WORKING WHAT SHOULD I DOOOOOOOOOO
Can we use multiple Gas detector sensor with Arduino
Yah
How
hello, i had been follow all the step and try it but the module MQ 2 and the LCD is'nt on. can you help me?
SAME PROBLEM WITH ME
Hey again bro can it detect smoke?
Yes
@@sritu_hobbyhi again bro can i use 220ohm?
Mage arduino ide eke if else danna bane. Error enawa. Hariyata dammath.
@@sritu_hobby libraries monahari thiyenawada . Download karanna
sir my program is showing a error of
Compilation error: LiquidCrystal_I2C.h: No such file or directory
pls sir tell me what to do
Include the library files
SIR I HAVE DONE EVERTHING BUT MY PROGRAM IS NOT WORKING@@sritu_hobby
What gas should we pass to that sensor..pls reply
LP gas
Can I use MQ135 instead of MQ2??
You can try it
Does this detect smoke
Smoke like burning please reply🤔🤔🤔
Power kaha sa mil rahi ha circuit ko
(Sayad computer)?
USB power
i've done everything you did and everything works exept for the display and I dont know why
Check jumper wires
@@sritu_hobby i checked and they are correctly connected, i literally copied your code, i don't know why it doesn't work...
The LCD display is showing the value but my led and buzzer isn't working..Can you help?
Check jumper wires
MY LCD IS NOT DISPLAYING THE VALUE CAN U HELP ME
sir my project buzzer is working but still lcd and led light is not working can you please help me through this

What is resistor
180 ohm resistor
Can use lcd1602?
Yes
@@sritu_hobby Can I use another resistor?
You can try it.
Bhai code work nhi kar raha ha error aa rha ha
You have to visit arduino basic tutorials
em xin code với được k ạ
