in this part

b707 · August 11, 2022, 6:42pm

The number of right and left curly braces does not match.
Format the code in the Arduino IDE with ctrl-T - it will be easier to find the extra or missing bracket

BitSeeker · August 11, 2022, 6:47pm

Yup, something goes awry after function byte potassium(){ } I think.

faqsycs · August 11, 2022, 6:57pm

is not work, still error

Go back and read Post #8.

faqsycs · August 12, 2022, 3:48am

what it mean, i don't understand

sterretje · August 12, 2022, 4:24am

  Serial.print("Potassium: ");
  Serial.print(val3);
  Serial.println(" mg/kg");
  delay(2000);
}

That last } is where loop() ends. Everything up to the below } is outside a function.

}
byte nitrogen() {

If you remove the first mentioned } that indicates that loop ends, it's one problem less.

faqsycs · August 12, 2022, 7:17am

can you correct all the code, need it ASAP

b707 · August 12, 2022, 8:08am

You do not want to learn to understand the codes a little bit? This is clearly not the last mistake - you plan to ask everyone on the forum?

faqsycs · August 12, 2022, 8:18am

i've try all script code for 2 weeks, but still not work
i don't know how to finde the wrong code, because it's first time make monitoring system on NPK sensor, and i don't know what should i do

sterretje · August 12, 2022, 9:14am

I think that I've given the correct pointer for you to fix it.

You have to wait till I'm or somebody else is in the mood, specifically after using the word ASAP. ASAP often results in people being reluctant to help; either it's a school assignment or you get paid and we don't.

Nothing is urgent on the forum. If you need it urgent, you can consider to pay someone to do it.

in0 · August 12, 2022, 10:38pm

@faqsycs pay special attention to the indentation of the code that is produced by the Arduino IDE's Tools > Auto Format (Ctrl+T). This provides a nice visual representation of the overall structure of the program.

I think if you look carefully you will see that the indentation of parts of the code does not match your intended program structure. This will point you to the error.
