A few Arduino Uno error messages i dont understand

Projects Programming

You have too many }'s in the end of your code. You could easily spot this out if you hit [ctrl + T] which auto-formats your code.

22

AWOL:
Is the print in the book unclear or really small?

It's not too bad...

23

Remove the comma after sensorVal.

heres what i have now--

Arduino: 1.7.10 (Windows 8.1), Board: "Arduino Uno"

L0M_Arduino_Task_3.ino:56:1: error: expected declaration before '}' token

Error compiling.

const int sensorPin = A0;
const float baselineTemp = 20.0;

void setup() {
Serial.begin(9600); // open a serial port

for(int pinNumber = 2; pinNumber<5; pinNumber++) {
pinMode(pinNumber, OUTPUT);
digitalWrite(pinNumber, LOW);
}
}

void loop() {
int sensorVal = analogRead(sensorPin);
Serial.print("Sensor Value: ");
Serial.print(sensorVal);
// convert the ADC reading to voltage
float voltage = (sensorVal/1024.0) * 5.0;
Serial.print(", Volts: ");
Serial.print(voltage);
Serial.print(", degrees C: ");
// convert the voltage to tempeartire in degrees
float temperature = (voltage - .5) * 100;
Serial.println(temperature);

if(temperature < baselineTemp){
digitalWrite(2, LOW);
digitalWrite(3, LOW);
digitalWrite(4, LOW);

}else if(temperature >= baselineTemp+2 &&
temperature < baselineTemp+4){
digitalWrite(2, HIGH);
digitalWrite(3, LOW);
digitalWrite(4, LOW);

}else if(temperature >= baselineTemp+4 &&
temperature < baselineTemp+6){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, LOW);

}else if(temperature >= baselineTemp+6){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, HIGH);

}
delay(1);
}

}

Read previous reply #20.
Start using code tags.
I can't force you to read the readme, but I can give you a time out to give you the opportunity.
Unfortunately (for you) the shortest time out I can give is a day.

26

Where'd you get 1.7.10?
The Arduino.cc IDE is only at 1.6.9:

Are you mixing up with Arduino,org IDE?

27

honestly im really confused rn. Just plz tell me what i need to do to get rid of the 1 error message i have left--

digitalWrite(4, HIGH);

}
delay(1);
}

}

Remove the last }

Are code tags really that hard to understand?

29

thank u thats all i needed.
Thanks for all the help, it compiled (and i read the readme)
Peace

lmao.
