Create a Infrared transmitter for any portable mp3 device, ie phones, music players ir transmitter for ipad 2. This tutorial is for creating the Infrared transmitter only. The way this transmitter works is it sends infrared on and off signals from the audio playback coming from your headphone jack.

Having saved an audio file with the correct on and off timings, you can play back this audio track through your portable music player and trigger infrared devices. This transmitter works better with a WAV audio playback, ir transmitter for ipad 2, however this has been successfully tested as an MP3 audio track.

To better illustrate this the left channel will play an on and off signal., ir transmitter for ipad 2. The Items needed for this DIY project are. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The first thing to do is strip the wire ends then twist the ground wires together. The ground wire is usually the wire unprotected by a coloured casing.

Connect the two infrared LEDs to the left and right channel. Make sure the two LEDs are in reverse from one another. As long as the LEDs are opposite from one another the signal should work. Once this is done bend the LED wires up to prevent the headphone jack wires from slipping loose. To clean up, we need to place electrical tape around each of the exposed wires. What I've done is tape up the Left channel and RIght channel separately and place another tape around the ground wires to prevent any unwanted wires being crossed.

Once this is done you are ready plug it in any portable music player to playback an audio track with infrared timings, ir transmitter for ipad 2. Reply 8 months ago. Reply 2 years ago. Hi Could someone please explain why 2 LEDs are needed? Ir transmitter for ipad 2 it work with just 1 LED?

All my TV remotes only have Reply 3 years ago. Two leds create the needed Hz "lightwave", while audio devices can at most support Hz audiowave. Reply 4 years ago on Introduction. I read somewhere that you'll double the frequency range by using both channels and reverse one. You'll basically double the amount of peaks from your transmitter.

Reply 3 years ago on Introduction. Couldn't you just as easily use two regular diodes between the left and right signal with the positive of the LED connected in between them?

The only concern I would have about this would be the LED possibly discharging the circuit too soon?. The main benefit of the diodes which I could see in this version would be that the LED will not flash until a voltage threshold is reached. Instead it will only drop negative when there is no "ON" also it will drop negative just after the "ON" signal and it will stay there until the next "ON". Even without the diodes, if you combine the left and right signals you will still end up with effectively twice the sample rate compared with a mono signal because each channel can carry on or off signals, ir transmitter for ipad 2.

So if the signals are combined then either channel can carry the "ON" signal and the net effect would be the LED flashing. In this case the negative voltage drop on both channels would be because of the one way ir transmitter for ipad 2 flow nature of diodes even ones which emit ir transmitter for ipad 2there would be no protection from differential signals in this circuit.

I don't see why this wouldn't work, too, so long as the software is designed around a mono signal. If it's really about setting up some sort of frequency cascade, or something else, I would like to see some evidence or something.

Somebody set me straight with a link! This would still allow the signal to move forward at all times until the frequency is enough to discharge the LED. I read the patent and I'm pretty sure I follow the logic. I still don't understand why this is necessary.

Is it because the pulses of an IR remote are so fast that a single on-off signal cannot be generated fast enough via an audio signal? They don't look so fast the blink patterns. Provided that when the audio tone pulses the voltage rises high enough and fast enough for the LED to emit. Also the voltage must drop quickly enough that the light is out long enough to actually pulse.

I think it would be much easier to just use a pwm output although that is probably defeating the whole purpose Please tell me. Thanks for it. I found that the VCSEL nm ones from optical mice don't like being overloaded and turn into expensive 0. If you are unsure its best to simply use the time honored techinque of putting an inline resistor and reverse polarity protection diode to prevent it from being damaged. It would probably also work well with DVB-T sticks that have lost their remotes, without which the stick won't turn on so Windows can install the driver.
