Hello. Why am I getting compile error...'loop' collect2 error: of returned 1exit status return code is not 0
the sensor is not glowing after uploading the code even though the connections are right. Can u plz solve it?
There is a problem with compiling
While compiling it says that there is no directory for mq2
You need to uninstall any previous library that you have used for the MQ2 sensor and use the one that we have given.
Thanks alotttt
Can you help me fix this?
MQ2_LCD:11:13: error: no matching function for call to 'LiquidCrystal_I2C::begin()'
lcd.begin();
I guess you have the wrong lcd library.
Try the one that we have given by first removing any previous lcd library.
Just cancell begin and write init at that place
what does "LGP" stand for?
We can't able to get the code
Sir, what is the input and output of gas sensor?
How can we add a buzzer if the smoke value increases
Yes it can be added if PPM reaches a certain amount.
DID NOT WORK
Sir...can u gift me for this code?
hi
Hello.. how to add parameter?
What parameters?
@@INOVATRIX does the mq2 sensor only read co, lpg, and smoke, or can other parameters be added? sorry I use google translate
No you can't add other parameters other than the ones you said
@@INOVATRIX but, can you add another type of sensor, which parameters are different?
For another sensor there will be a whole new code for it.
no compila
Try to add all library files and updated version of arduino IDE
