IR send for Carrier Air Conditioners

Using Arduino Programming Questions
#1

I was trying to write the sketch to send the code for an carrier air conditioner, but, when I received the signal by the arduino, I got this code:

How I will write the irsend to send this code for the air cond?

Does it give you the same 32 bit number each time? I’m assuming the second one did show a hex code of some kind and you just left it out, right? If you get different encodings each time, then I can’t help you…yet. I have the same problem with some kind RECS format or something. I can’t get the IR library to understand the Uverse stuff. It gives me bizarre readings that change each time. Must be longer than 32 bits.

Hi, I'm new here but I have work a little with IR and Arduino.

What I understand is that you have is a dump of raw signal.

You can read it here

Don't forget to "clean" the code, remove every - (minus), add , instead of space

And this is a very good place to start :slight_smile:

The Hex codes , which i receive is the same everytime. :slight_smile: but the raw data varies ..

Now How should I, write the irsend to send this code for the air conditioner?

ya thanxs cazz

i had load my raw code into your smaple sketch , but when i observe with cam there is no ir signal is coming from IR led which is connected at pin 3 , i am using freeduino board with atmega 328 p controller

now what am suppose to do , please help me...

#6

i think tehre is a problem with pwm pins , how to activate pwm pins in freeduino i.e. arduino duemilanove atmega328 , so i can send my singals to airconditioner

#7

What IR library are you using? How are you getting the raw data?
The raw data is not needed. It will vary depending on the brightness if the sender.
Only the first number 'code' is needed.
