A friend of mine came yesterday to me asking if I can do something for him to control WinAmp via a Remote Control. After some searching I found a very simple to build IR receiver using the serial port on LIRC official page so I started to gather the components from our local electronics shop. It costed me around 1.5$ so it was also cheap enough 
.
The schematic is
and the components are as follows :
- IC1 = 78L05, 5V regulator
- IC2 = TSOP1738 , IR receiver
- D1 = 1N4148
- C1 = 4.7uF
- R1 = 4.7K
- one male or female (depends on your configuration/cables) serial (DB9,RS232) connector
I choosed to put all components on air and in the serial connector’s box (photos below).
The pinouts of the 9-pins connector are :
- 1 = DCD (Carrier Detect)
- 2 = RXD (Receive Data)
- 3 = TXD (Transmit Data)
- 4 = DTR (Data Terminal Ready)
- 5 = GND (Ground)
- 6 = DSR (Data Set Ready)
- 7 = RTS (Request To Send)
- 8 = CTS (Clear To Send)
- 9 = RI (Ring Indicator)

- Girder – free trial, can be buyed for about 40$
- WinLirc if you are on Windows and Lirc if you are on an UNIX platform -freeware
- WinAmp Plugin for WinLirc
- BSPlayer – a very good video player, it have a built-in support for WinLirc
(Edited) As a remote control you can use almost all universal remote controls (you must know its working code for the TSOP1738, for the one from the attached picture the code is 081) and most of the domestic (videorecorder, tv …) remote controls. To see if one is working open WinLirc, press Reconfigure and then Raw Codes. If when you press a button on your remote control you see lots of numbers there then it means it is working.
(Edited) To add a status LED to your receiver, just make the schematic below (I tested it last week and it went ok). The disadvantage of this is that you’ll need a battery so it can run ok.
Just click the image to see it larger

can i use tsop1556 here
As long as you have a remote for it, yes.
Here is the description of the TSOP 1556 :

and please tell me about pinout of tsop1556
You can see it in the link I gave you above.
Hope this helps

My PC do not have Serial port and most of the new PCs don’t. Do you guys think this will work on a LPT or Parallel port?
According to the WinLirc page (http://winlirc.sourceforge.net/) : “Note that the parallel port hardware, …, are not yet supported by WinLIRC”, but, if you use Linux you are lucky : http://lirc.org/parallel.html
I have an IR led receiver, can I use that or do I have to use your little IC? (The TSOP)????

You need to use the TSOP as it is a specialized IC for this job.
Hope this helps

Hey i downloaded GIRDER ( free trial ). But its not detecting when i press my remote button. Does this need any plugins.
Hi,
I was working excellent with Girder 3.3 + igor’s plugin during years with one JVC remote and a gml file I donwloaded from the internet.
Now the remote is not working anymore and I tried to “learn event” with every remote I have in my house and the same happens: the code is changing every time I press a button.
I can’t get it works like in the past and I am desperate for use it again.
I tried with the anti repeat wait time (200, 500 1000 ms) and nothing.
Even I tried to build manually my gml file but it was imposible to understand the way (is there any tutorial?)
Please, help!
thanks in advance

Wondering if you could respond to post #42:

hi..
why u have used the DCD and RTS pins and NOT the RXD pin which is involved for receiving data..??
and how DCD and RTS funtion in the above circuit.?
thanks
Hi
I just want to know is there any possibilities to find out frequency of my remote control (SONY RMT-814). I build a infra red receiver from your site but it didn’t work with my remote controler. I think it’s because my remote control is using differnt frequency(my ir receiver use 38kHz freq).
Bye

Hi,
I saw with interest this circuit. I am interested in reading the IR codes in HEX so I can paste it in other RC applications.
Is this possible using winlirc?
Cheers
Sorin
hi, i have a question, how long of the 3 lines wire can i use?
i talking about 50ft
will it still work?
thenk u.
Hi
Sorin Toma .. I think it is possible, just take a look on WinLirc/Lirc support forum and I’m sure you’ll get it working.
Saul … I don’t know exactly but my longest cable was about 5 meters long (about 16ft)
Hope this helps
Sorin
What can i do in order to make it work for about 15 meters?
can i change the C1 maybe for a more powerfull one?, so the system won’t lose power?
and where is it better to put the commponents (C1, R1, D1, IC2) at the beggining? (next to the computer) or at the end, with the IR Reciver? (in order to give the system more chance to work for that long disstance cable)
thanx.
Hi, i don’t get it work
Maby is problem -5V volts in computer hardware, cause it shows 3,5 only not 5v, is this problem?
just stop plaing with toys … do something real stuff …. like usb receiver
Hi, can I simply get an old mouse IR detector and build the circuit?? Will it work?? Anyone had already tryed it??
Thanks!!
hey gr8 circuit dude i made it nd its workin but my laptop doesnt have a serial port and hence i want to d the same with usb port since i m an ametuer in electronics so cant make the circuit mentioned by u above(in one of your posts) so can i use a usb to infrared port for the same
plez help
i have tried the “Learn how to control everyone’s favourite XMMS with a TV remote ” pdf document in the “howtos” page of ww.lirc.org but i have not been successful…
i connected the circuit and soldered it…….but my device doesn’t respond when i press buttons on my remote…..is there any specific range of choosing remotes…….and i connect the circuit to the serial port…..i am confused with configuring the device using ./configure……..i donot know the port nuber to which i should connect this device…….i think this device sits only in one port…..i want to know the port number of the device….
i use fedora core 3…..so as told in the manual i did not recompile the kernel as i found the files specified in the location….
i do not understand the problem……please help me…..
thanks

does using a 7805 voltage regulator effect the circuit
Hi Fisher … no, you can’t just use those photo detectors, you need a specialized IR detector running on the frequency of your remote control.
Hi Arjun … you can buy a small USB to serial converter or make an USB receiver (please look at the post number 6 from this page)
Hi sandeep … 7805 is fine (the only differences are the package size and that it is rated at 100mA, if I’m not wrong), I used it also when I didn’t find to buy 78L05. As for your other post .. sorry, my Linux knowledge is very limited.
Best wishes
Sorin
You may want to clarify in your post that R1 = 4.7KOhm (not just K). When I saw just the K I was confused for a little while!
Instead of making the above circuit con you give me the simple TSOP1738 receiver circuit and an IR transmitter circuit….plz reply me on
For IR transmitter circuits you can take a look at http://www.lirc.org/transmitters.html , they are really simple to build
As for the receiver, this is the simplest safe schematic you’ll find.

hi
I have created Ir reciver successfully Now i want to make its contolling software of my own any help ?
I also tried doing that in Visual Basic 6 some time ago. I used WinLirc as a server (just as the WinAmp plugin does).
Anyway, if you want to build an application from 0 you can take a look at WinLirc as it is open source.
Please keep us updated on your progress.
Sorin
first of all thanks for ur reply i m trying to make software in Vc++ and have gone through WinLirc infact using it for testing but i am not able to understand a single code in WinLirc files any help plz.
Can u tell from where i can understan there codings any site link etc .
Nice device!
For the sake of information sharing, I used the IR-receiver from Everlight, IRM-8601S, and it works just fine!
A question:
It’s too complex to append a LED, to the circuit, that lits when a signal is recieved and then un-lits? (Excuse my english)
what is the type of wires you used ? and you only connected to DCD GND RTS pins and left all other pins without any wiring?
For adding a LED .. hmm, I’ll give it a try in the weekend and post here the schematics but .. it will mostly sure need an external battery (3V cell) just to be secure.
Ali .. yes, only those 3 pins are needed for WinLirc.
Regards
Sorin
thank u for ur fast reply , do i have to use cd rom audio cable to connect or what kind can be used?
You’re welcome
, but you can also use normal telephone cable which has 4 wires (just let one unconnected).
You can use any type of cable, i found at our shop cable on 3 wires which is perfect
thanx again and wish u good luck in ur futural projects and keep amazing us with beautiful things
Trimbitas, I found this in the mailing-list of LIRC (from Bill Paxton):
——————————————-
Disclaimer:
Please remember this is a serial port. Like always if
you fry something – whoops. Your bad. Besides this
could be a trick and I want you to destroy your serial
port. Beware.
Parts:
1 – low current (~2mA) LED of your choice
1 – 3.3k+ resistor of your choice
Directions:
Wire LED+ to the resistor. Wire other side of resistor
to detector input pin. Wire LED- to detector output
pin. Done.
Notes:
This is really not that bright, and I mean
intelligence not millicandelas.
It /must be/ a low current LED. We shouldn’t use more
than 1mA. Already there is a Vreg(~3mA) and a detector
(~3mA) plus if you use the 4.7k pullup resistor,
another ~1mA. Measuring one on the table right now
using an L78L05, PNA4602, and a 4k7 pullup it’s taking
6.2mA from RTS.
3.3k ohm would allow 1mA if it were constant and the
LED was 1.7Vfd so it’s less really. If you don’t need
the brightness by all means increase the resistor.
PLEASE do NOT take advantage of the fact that it is
pulsed and lower the resistor. You probably can, some.
But for the record “don’t do it.” (if you make it too
low or omit it, your detector will stop working
because it’s ‘stealing’ all the output)
——————————————-
If this works it seems that the kind of solution I have looking for
What do you think?
(I’m gonna try it when I have the time)
its very nice .
please send me the full project
Hey, I must write a program in C# where I must write and read data from the serial port, but the communication must be wireless. Do you have a sender that will work with your receiver circuit?
thanks
Trimbitas,
May I have permission to use the schematic at the MythTV wiki? I’m working on IR docs and how-tos there and could use a sharp graphic like that. I’ve already linked in your, IMO, superior writeup on the matter.
TIA
Ol Schoola … yes, you have my permission to use it.
As for adding a LED … a little later today or tomorrow morning I’ll put working schematics (just to have some time between unpacking my stuff).
i want to do it using usb port,
would you like to help me ?
I just added the status LED schematics (it works 100%, tested it).
Papai … there is an USB version on http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm

Sorin
hi,
i try to do tre ir reciver, but till i can not able to make it .plzzzzzzzz ,someone help me
plzzzzzzzzzzzzzzzzzzz.
Hi ,
Could not find the circuit for adding the status LED ?
papai .. what exactly aren’t you able to do?
Ashish .. it is at the end of the post ( just above all comments )
Hi,
my ir receiver is working & signal is detect by winlirc.
But problem is that I do not have the idea how to write script For control the volume, mouse movement power off, Enter, previous, next, open jet audio etc.
Please someone sent me those scripts.
My add : repapai143 ( at ) rediffmail.com and leglegi ( at ) gmail.com
For those looking to do a USB version, this SourceForge project is very nice, and even has an optional LED in their setup.
http://usbirboy.sourceforge.net/
I ordered parts to build 25 of them for me and various friends and family and it came out to about $4 each. It’s more than this sereal device, but not too expensive. To build just one would be a bit more though.
SOME ONE PLZ. HELP ME ABOUT SCRIPT FOR MOUSE CONTRAL
hi
my serial port does not work
thats-why i need a tecnique
by which it can works with
usb
