Printing many variables in the serial monitor

Projects Programming
1

As the subject states, I want to print three variables one line on the serial monitor and then have them print again on a new line after.

This is my code

int pin, pin1, pin2;
void setup() {
Serial.begin(9600);
  
pinMode(A0, INPUT);
pinMode(A1, INPUT);
pinMode(A2, INPUT);

  }
}

void loop() {
  pin = analogRead(A0);
  pin1 = analogRead(A1);
  pin2 = analogRead(A2);
  Serial.println(pin + pin1 + pin2);
}

The serial monitor displays the sum of all three variables (pin + pin1 + pin2) instead I want them to be displayed separately (pin1, pin2, pin3)

I tried to use Serial.println(pin, pin1, pin2); but that gave me this error:

exit status 1
no matching function for call to 'UARTClass::println(int&, int&, int&)'

Why are you ADDING the values? It doesn't seem to difficult to figure out that you need to print them using separate calls to Serial.println().

Serial.print(pin);
Serial.print(pin1);
Serial.println(pin2)

marco_c:

Serial.print(pin);

Serial.print(pin1);
Serial.println(pin2)

The problem with that is what does

mean?

Why not add the values, as do Frank and Earnest?

True, good catch Paul. You need to add a space between them :slight_smile:

Just more printing.

try this :

Serial.print(pin); Serial.print(" ");
Serial.print(pin1); Serial.print(" ");
Serial.println(pin2)
