"Power" = 33121 + 5S
"Mute" = 33121 + 2S,2L,1S
"Channel Up" = 33121 + 2S,1L,2S
"Channel Down" = 33121 + 1S,1L,3S
"Volume Down" = 33121 + 1S,1L,1S,1L,1S
"Volume Up" = 33121 + 3S,1L,1S
"AV/TV" = 33121 + 1S,3L,1S</p><p>To summarize the above, if we assume the Short pulses represent binary-0's, and the Longs are binary-1's, then the command codes are:</p><pre><code>Power = 0b00000 (0x0)
Mute = 0b00110 (0x6)
ChUp = 0b00100 (0x4)
ChDn = 0b01000 (0x8)
VoUp = 0b00010 (0x2)
VoDn = 0b01010 (0xA)
AVTV = 0b01110 (0xE)
</code></pre><p>Then after that it (presumably) spews out codes from other standards for the pushed button, whatever they are, they are reproducible.</p><p>Lastly, I implemented a few sanity checks to prevent fussing over clearly-malformed pulse chains:</p><ol>
<li>Confirm that the first two pulses' durations are <= 90.</li>
<li>Confirm that the pulse durations "clump" into easily identifiable "Long" (~45-85) and "Short" groups (~25-40).</li>
<li>At various points in the pulse chain, there is a mystery pulse with a duration of specifically 215-225 (usually ~220). It's much too long to be a "Long" pulse (= max. of 80) and much, much too short to be a Gap (min. of 1370). To simplify things, I arbitrarily declared such in-between pulses to be "Long" ones.
<ol start="4">
<li>I currently have my program to capture and match 130 pulses and discard the rest. With a fresh battery, this Remote will spew multiple hundreds of pulses per button push. So when I see the program suddenly start saying, "66-pulse IR signal received" (instead of 130 pulses), I know it's time for a new battery, as it also suddenly starts failing my Sanity Test #1 above.</li>
</ol></li>
</ol><p>Let me know if anyone wants to try this program with the currently-on-sale Remote.</p></p>

I wrote a program to capture the counts of first 120-ish "Long" and "Short" pulses, as follows, where -1 is a placeholder to keep the Longs balanced with the Shorts, and -2 means "Switch to Short pulses come first after a Gap.":<pre><code>// For brevity, as much as possible, I'll express each button's
// pattern as pairs of:
// <so many> Long pulses, <so many> Short pulses.
// -1's are placeholders, for when there is no Short pulse
// preceeding a Gap, etc.
// -2's mean, Short pulses come first after this Gap.

I'm looking for a simple way to use IR transmitter / receiver pair to turn a circuit on / off. It's been years since I've done circuitry / micro-processor code.</p>

Maybe if you just hold the remote upside down... no, wait. If you stand on your head... no... hmm..</p>

By holding down the mute button, the remote will send out every mute command it knows (a lot). When your TV mutes in response to the remote, let the button up and then press mute momentarily again. As a result, the remote learned the code set for your TV and the remaining buttons should work.<p>When the remote is first powered up, it sends several codes for each button � three NEC-standard codes (or similar) plus others. After programming, it still may send more than one code per button. The mute codes come fast during programming and there may not be enough resolution, given you reaction time, so the designers just send a few nearby codes.</p><p>To de program, leave the battery out for a while.</p></p>
Richiep on COM-10280 - Infrared Keychain Remote ControlRichiepurn:uuid:a469a710-617c-5901-d10d-9baf75cae3d92012-02-11T08:20:29-07:00<p>I set this up with my Arduino to control some high powered LEDs and it worked great. My project can't work in the living room though because this remote controls my TV as well.<p>I then played around with the other remotes in my house and found that they could not control the Arduino. This suggests that the universal codes are not so universal.</p><p>So I tried to teach my learning remote the signal from the key chain but it couldn't learn the signal. After I gave up on this I discovered that the key chain no longer worked on my Arduino or TV which were both getting a signal. It appears that I have reprogrammed the key chain.</p><p>This leads me to believe that one of the two IR emitters on the key chain is actually a receiver.</p><p>Sparkfun - Please give us a datasheet.</p><p>Thx

Maybe the slower baud rate took up more time causing the arduino to miss the next repeated incoming stream of data?<p>I also noticed that one LED was not blinking</p></p>

But heck, it was $4 and it still works.</p>

if you replace it with a better one or two or somehow modify it in another way you should have a bit more range.</p>

I tested it at 18 feet and it works.<br>
BUT I only have one IR LED working out of 2! I check with a iphone and saw only one lighting.<br>
Leave baud rate at 9600 and it works. If you try at 115200 baud you read the signal faster and get everything in double like this:<br>
