hi all
anyone pls advice
i have some trouble here
my project is automatic air conditioner remote controller.
problem is .. i dont know how to stop looping on my coding when i put temperature in range value
coding:
//loop()
if (t>=25 && t<=40);
{
delay(5000);
irsend.sendRaw(raw23,216,38);
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
}
//
What do you want to happen when the temperature is in range ?
What do you want to happen when the temperature becomes in range ?
What do you want to happen when the temperature is not in range ?

I don't understand what you want.
In an Arduino program the function loop() should repeat quickly and continuously.
...R
if (t>=25 && t<=40);
oops
hi
what i want is.. ir sending one time to set the air conditoner to 23 C when temperature in range.. what happen know .. my coding are keep looping.. and keep sending ir to my air conditoner..
here is my code
if there are led myb ican use "else ... digitalwrite... low..
but know im using ir led..
and by the way im using arduino mega
#include "DHT.h"
#include <LiquidCrystal.h>
#include <IRremote.h>
#define DHTPIN 7 //Define sensor pin(pin 12)
#define DHTTYPE DHT22 //What sensor use

const int ledPin = 13; //LED pins for temperature control
long previousMillis = 0;
long interval = 1000; //Read sensor each 2 seconds

This is just plain stupid. The ONLY excuse for putting the { on the same line as the function/statement that holds any water is that it saves real-estate. Then putting forty-leven blank lines in the function makes no sense.
Jamming everything up against the left edge, instead of properly indenting the code, makes no sense.
I'm not even going to attempt to read that code.
Using Tools + Auto Format, reasonable white space, and code tags costs nothing, but it does keep you from looking like you don't give a damn.

what i want is.. ir sending one time to set the air conditoner to 23 C when temperature in range.. what happen know .. my coding are keep looping.. and keep sending ir to my air conditoner..here is my code
First, to make it easy for people to help you please modify your post and use the code button </> so your code looks like this and is easy to copy to a text editor. See How to use the Forum
If you only want to send a message once then create a variable to count how many times the message has been sent.
