The function of the device is very simple. Any IR remote than can be programmed to use the Sony protocol will work. The module outputs the device code (TV/VCR/DVD/AUX) and the button pressed, so the device can be used on as many different projects as your remote has devices (usually four). The numeric keys output the number of the key (0 outputs a 0, etc.). The function keys all output unique numbers. source

This project can steer 10 different things wireless with the use of a normal TV-remote-control with the RC5 protocol, from manufacters like Philips, Grundig and Marantz.If the Proton PIC Basic compiler is available, then you can ofcourse change the number of channels.When ‘TV’ mode is selected on your remote-control, you can with the buttons 0 through 9 on it, steer 10 outputs on and off.When there is an unused system on your remote-control (SAT, AMP, DCC, VCR2) then the code in the PIC can be changed with the remote-control to another system.source

This project is an expansion from another project .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.Besides is for this project a PCB layout drawed to make it still more easier for you.The circuit based on PIC16F628A.source

Here is a wireless controlled light dimmer.When you switch the power on there will follow a soft-start till the lamp burns at the previously adjusted dim level.With the ’0′ button in TV mode you can dim the lamp, turn more and less bright.The remote control should send more then one RC5-signal per button-press seeing that the first one is ignored, this does imply that when the remote button is pressed a short time, there nothing happens.source

If you need to use an IR Remote control through the phone line check out this idea because of the signal transmitted by a remote control usually consists of serialized binary data, which is modulated at about 38KHz. The receiving device converts the modulated infrared light into electrical impulses, demodulates and processes them to obtain digital codes corresponding to the data being sent by the remote control. source
