LCD menu

Im trying to find a way to enter my code an LCD menu
To enter the temperature and fan settings

#include "DHT.h"                        
#include <LiquidCrystal.h>               
#define DHTPin 2                        
LiquidCrystal lcd(1, 3, 4, 5, 6, 7); 
float tempC;  
int fanPin = 8;
int ledrPin = 13;
int ledvPin = 11;
int heatresestancePin = 12;
char buzzer = 9;


DHT dht;


void setup() {
 dht.setup(DHTPin);  
 lcd.begin(16,2);
 pinMode(fanPin, OUTPUT);
 pinMode(ledrPin, OUTPUT);
 pinMode(ledvPin, OUTPUT);
 pinMode(heatresestancePin, OUTPUT); 
                 
}
void loop() {

 float tempC = dht.getTemperature();
 float humi = dht.getHumidity();
 
 if (tempC >36)
{
digitalWrite(fanPin, LOW);

 digitalWrite(ledvPin, LOW);
 
digitalWrite(ledrPin, HIGH);


 for(int note=700;note<2000;note++)
   {
   tone(buzzer, note, 125);
   delay (1);
 }
 for(int note=2000;note>=700;note--)
 {
   tone(buzzer, note, 125);
   delay(1);
  


 }
}
else
{
{
digitalWrite(fanPin, HIGH);

 digitalWrite(ledvPin, HIGH);
 
digitalWrite(ledrPin, LOW);


 
}
if (tempC <37)
{
 digitalWrite(heatresestancePin, LOW);

}
else 
{
  digitalWrite(heatresestancePin, HIGH);
 
}
 lcd.setCursor(0,0);
 lcd.print("Temp: ");
 lcd.print(tempC);
 lcd.print(" C");
 lcd.setCursor(0,1);
 lcd.print("Humi: ");
 lcd.print(humi);
 lcd.print(" %");
  delay(2000);
}

}

OK, first things first.

You need to go and read the forum instructions so that you can go back and modify your original post - the "More -> Modify" option below the right hand corner of your post - to mark up your code as such using the "</>" icon in the posting window. Just highlight each section of code (or output) from the IDE and click the icon. In fact, the IDE has a "copy for forum" link to put these markings on for you so you then just paste it here in a posting window.

Do not attach it as a ".ino" file. People can usually see the mistakes directly and do not want to have to actually load it in their own IDE. And that would also assume they are using a PC and have the IDE running on that PC.

But don't forget to use the "Auto-Format" (Ctrl-T) option first to make it easy to read. If you do not post it as "code", it can be quite garbled and is always more difficult to read.
