Error Codes

Projects Programming

Hello Everyone,
I am new to programming and trying to learn the ropes. What I am trying to accomplish is, control a humidifier with a relay. I based my code off of a video. What I want the code to do is read the value coming from the DHT11 sensor and and turn the relay on if it is high than a set value. So I wrote/borrowed the following code. I get the following error code - Arduino: 1.6.1 (Mac OS X), Board: "Arduino Uno"
(code tags added by Moderator - please use them in your future posts)

DHT11.ino: In function 'void loop()':
DHT11.ino:62:1: error: expected '}' at end of input
Error compiling. "

//    FILE: dht11_test.ino
//  AUTHOR: Adam Zabielski
// VERSION: 1.0
// PURPOSE: Humidifier Control Module
//

#include <dht.h>

dht DHT;

#define DHT11_PIN 2

int Humidifier = 4;

//Onborad led
int led = 13;

int i = 0;

void setup()
{
  Serial.begin(115200);
  Serial.println("DHT TEST PROGRAM ");
  Serial.print("LIBRARY VERSION: ");
  Serial.println(DHT_LIB_VERSION);
  Serial.println();
  Serial.println("Type,\tstatus,\tHumidity (%),\tTemperature (C)");
  
  pinMode(Humidifier,OUTPUT);
  pinMode(led,OUTPUT);
}

void loop()
{
  // READ DATA
  Serial.print("DHT11, \t");
  int chk = DHT.read11(DHT11_PIN);

  // DISPLAY DATA
  Serial.print(DHT.humidity, 1);
  Serial.print(",\t");
  Serial.println(DHT.temperature, 1);
  
  //Relay Control 
  
  if (DHT.humidity<55) {
    digitalWrite(Humidifier,LOW); 
  } else { digitalWrite(Humidifier,HIGH); 
  
  }
 // Deley and LED flashing 
i=0;

while (i<10) { 
  digitalWrite(led,HIGH);
  delay(1000);
  digitalWrite(led,LOW);
  delay(1000);
  i++;
}

// End of code

Thanks for taking a look.

All the { } must pair up.
All code must be in a function - setup() and loop() are considered functions as well.

This 2nd } here

  if (DHT.humidity<55) {
    digitalWrite(Humidifier,LOW); 
  } else { digitalWrite(Humidifier,HIGH); 
  
  }
 // Deley and LED flashing

closes out the loop() function.
All the code that follows is then Not in a function. Move the 2nd } to the end of the sketch.

This 2nd } here

That is why you should NEVER put the { next to code. Put EVERY { and every } on their own lines. Keep your code properly indented (or use Tools + Auto Format) and your see where functions and blocks start and end, and you won't have multiple things ending at the same place/prematurely.
