Hi,

If you are using the code from the Libstock you should be able to write in the LCD before you reach this line.

As I told you we do not have the same sensor. But the principle is the same and it should be like for the MQ-8 sensor.

Read the ADC value of the sensor and calculate the PPM, make the conversion to the string and write the value one the LCD.

Best regards,
Aleksandar

thank you sir. i think that formula is for the calibration right?
ok now my problem is when i try to read the value from the adc input, it gives random numbers.
