Hello Bryan:

The way it was explained to me, the FF was the start of the packet, kind of an “ATTENTION” line at the beginning as a way of telling the receiver to wake up and pay attention to the next flashes of light (timing) for the packet.

Hello Vincent:

Your best bet would be to see be to reset the cable box by performing a powercycle on it. There is not a remote command on most cable boxes that will force the cable box to reset itself so you’ll have to build an arduino controlled switch that you can control over the Internet (or via a computer at home). It sounds like an interesting project. Let me know if you decide to do this.

Good Luck!

Hello Brad:

I would check for any sources of IR light (incandescant bulbs, windows, bright lights, etc). In my testing, I was doing this in a windowless room with a fluorescent light as the only other light source so it was easy for me to get the codes. You may want to check your IR receiver and make sure that it’s working right. Easiest test method would be to hook the IR receiver up to an LED and make sure the flashing is pretty consistent. You only need to capture one code without interference to get a good read.

Good Luck!

tripped over an unexpected hurdle.
gotten the arduino responding to ir codes from several different remotes around the house, and all put out hex numbers into serial monitor.
unfortunately, the arent the same numbers each time.
there are a few garbage numbers, two or three numeric figures, but i kinda expected that.
the problem is, if i press any button it will repeat said code as expected.if i release and then press and hold the same button again, then it will repeat and entirely different code. release and press a third time, and it will repeat the first code.
weird eh?
am i missing something incredibly obvious?
thanks in advance.

why do we have to use the codes that start with FF?

I HAVE A SLING BOX THAT LETS ME VIEW CABLE TV ANYWHERE I HAVE ACCESS TO INTERNET VIA MY LAPTOP..
SOMETIMES I NEED TO PWR DOWN MY CABLE BOX WHEN IT GETS HUNG UP…THOUGHT I COULD SEND SIGNALS FROM VITURA IF TRANSMITTER TO HOME WHERE IT COULD DECODE AND SEND SIG TO TURN CABLE BOX POWER OFF AND ON,,,,I HAVE BEEN TRYING TO DO THIS WITH DESCRETE COMPONENTS,,IT IS DIFFICULT BUT PROGRESSING..
CAN U THINK I CAN USE ARDUINO TO ACCOMPLISH THIS MORE EASILY.. THANKS VINNY

Hi,
>>Mac users: I don’t know. If you figure it out, drop me a comment and I’ll add it here.

On Mac, the examples and library directory are inside the Arduino application package. Right click on the Arduino application icon, select “Show Package Content” to open it up.

I have a screen dump here:
http://dl.dropbox.com/u/219819/arduino/arduino_example_mac.jpg

Don’t link to it. It’s temporary.
Copy and use it on your server if you like.

Thx for the great tutorial.

Cheers,

Michael

Hello Lynxo:

I’ll look into it again, but my code copied and pasted from the article worked. Is it possible that your browser is converting the single quotes and double quotes to smartquotes?

As a test

” should be completely vertical, not leaning to either side. (double quotes)
` points up and left. (Backtick)
‘ points straight up (Single Quote/Apostrophe)

Thank you for letting me know.
