Universal RC5/RC6 transceiver

This project has two main functions on the one side you can read the RC5, RC5X and RC6 codes from remote controls on a LCD and on the other hand you can send all thinkable RC5, RC5X and RC6 codes to a device.

When the TSOP1736 (IR receiver) receives an infrared (IR) signal from a RC5 or RC6 remote control (like Philips) burns LED1 (green). The LCD shows when it receives a new type of code for one second which protocol is received (RC5, RC5X or RC6). After then the LCD shows the RC5 or RC6 system- and command code in decimal as wel in binair. The toggle-value is shown by LED3 (yellow). LED2 (red) burns if the received signal is poor or if it’s not a RC5, RC5X or RC6 signal.

With the IR-transmitter it is possible to send every possible code from the RC5, RC5X and RC6 protocol, like a remote control does.

 UIR - Universal Infrared Receiver Board Assembled

And here is another infrared receiver, although its name says its universal that doesn’t mean the other Infrared Receivers aren’t. The project page first presents a MCU version of the receiver based on several types of PIC’s and than the symplified version without MCU, the one i also wrote about here. The goal is the same as for the other infrared receivers, to control your computer with any remote controller you have (TV, VCR, CD or Stereo).

USB-IR-Boy Infrared Receiver Board and USB Cable

USB-IR-Boy is LIRC compatible USB bus infrared receiver hardware using Motorola MC68HC908 MCU. This project aims to be  the new standard  home made IR receiver with low cost for all PC hardware that has USB. In my opinion this project its not better than other infrared receivers, its just different by having USB connectivity and being based on a Motorola MCU. This project also has an extra item, the LED indicator, which blinks when signal is detected. Everything you need is provided on the site so you could give it a try if you need a infrared receiver.

Serial port infrared receiver

serial-port-ir-receiver

This project is really easy to build, anyone can try it. After reading this tutorial anyone can build this. You just need the tools and the parts list and you can start building it. I first build this project about 2-3 years ago when I found the schematic on a website I don’t remember which website, and I gave it a try. Surprise, it worked! And it worked fine.

The receiver it’s very sensitive, you can send signals with a TV remote from 10 m away very easy. You don’t even need to point the remote at the receiver, it’s so sensitive it picks the signal that bounces from objects or walls. And if you think at the cost of this project parts list, it’s really cheap, about $4. You can build this on a board or just connect the parts between them.

There are various modes of assembly of this project: you can build the hole circuit inside the RS232 connector so only the IR sensor comes out, or you can build the circuit inside the connector and attach a wire with the sensor at the end. You can assemble it however you want. This is the schematic of the receiver, you can see that it uses an IR detector, a resistor, a diode, a capacitor and an rs232 serial connector. Very simple indeed.

serial-port-ir-receiver schematics

If you take a look at the ir detector code the last two digits represent the frequency at which the IR detector receives signals. I successfully used different frequency ir detectors and all of them worked with any remote I had around the house. If you encounter problems with some kind of remote you should try changing the IT detector with one of another frequency(it is optimal to use the 38 KHz receiver).

After building the receiver connect it to your com port and lets talk a bit about the software part. The receiver needs a software that is going to decode the signals and control various other programs that you want to control. As a software you can use a free software named Winlirc or Girder which you can buy for about 40 $(note Girder must be use together with a plugin that recognizes signals coming from our receiver, the plugin is named Igor and you can download it from link1 or from link2 there are 2 versions available , you should try the first one and if that doesn’t works the second one will work).

I’m going to teach you how to use the receiver with girder and Igor plugin because this is what I used. After installing Girder you have to install the Igor plugin , if you encounter any problems you can check the plugin’s website for answers or you can write a comment here and I will be happy to answer you. Now after you plug in the receiver start Girder.

Now you have to go to configuration to hardware plugins and check Igor SFH-56 device and set the correct com port.(click Link to see a picture explaining configuration of Igor plugin).Now your software is ready to receive signals from the receiver. Now the small green led in the lower right side of Girder should blink every time you press a button on your remote signaling the software is receiving signals. Now all you have to do is start configuring Girder to control various other programs by learning different keys and their action. Here are some pictures of assembled receivers:

And here is the part list:

  • TSOP 1738 : ir receiver x1
  • resistor 3k3 x1
  • capacitor 100 nF x1
  • z diode 5v1 x1
  • rs232 conector x1


Infrared Remote control receiver circuit

    It seems that we like remote controlling stuff around the house. So why not control your computer remotely. Many people have turned their Pc’s into multimedia centers replacing their tv, dvd, mp3 player. But a multimedia center without a remote it’s not so good. There are a few commercial alternatives, but they are a bit expensive and are not totally adaptable.

    I have build a project like this which I will present in a future post, it’s a much simpler version of an IR receiver connected to the COM port of your computer and with the help of a plugin trough a software called Girder I successfully control almost anything in my computer. The IR receiver we are talking about now it’s a bit more complicated and more advanced, it uses ATtiny13 microcontroller.

    You have the possibility to turn on/off your computer and also control anything you like from your computer. A note to this project is that its only programmed to work with RC5 remote controls. If your remote control is made to work with RC6 code, or any other IR (InfraRed) system different than RC5, you will never make this circuit work. This is a nice project with practical applications, and its easy accessible to beginners. Click the Link to go to author’s webpage for details and schematics.
