do any one have anyproject ideas in INFRARED COMMUNICATION .any any , then please help me.i need it for my final year project.i am thinking of infrared LAN but if you have any good ideas then please tell.



  1. Build a IR repeater station, to control audio/video from your bedroom, for equipment used in the living room.
  2. Build a IR wireless headphone.
  3. Build a RS232 wireless connection set.
  4. Make your keyboard/mouse connection to the PC IR wireless.
  5. to 50. Use your imagination.
1 to 4 should be increasingly difficult. 5 to 50 even more so. :) PS: you can buy non-dedicated remote control sets, to use for any purpose. The last one I checked, had 10 buttons, and a reciever with 10 outputs.

Try some of the inexpensive IR components used for remote control of TVs.

See what sort of distance/bandwidth can you get for a very low error rate.

Try various encoding schemes.

See what happens in sunlight.

For extra credit, try a plasma TV. :) Can you find anything that works?

These are my opinions, not necessarily my employer's. I hate spam.

hi burry ..thnx for ur responce.

i thought of RS232 IR communication but my seniors hv done this project so i wanted 2 go for some new ideas.u told abt interfacing k/b or mouse with pc using IR ..cn this b done with simple k/b which we generally use.

Standard keyboard and mouse is almost the same as rs232, with some pins added to supply 5 volts to the devices. So its almost equivalent to implementing 2 rs232 inputs and one rs232 ouput, the keyboard is a two way serial, and the mouse a one way serial connection.

Done that, in a non-standard way though. I have an IR receiver from a spent DVD player connected to a simple 433Mhz SAW filter based trasnmitter (cut from a UHF remote from a satellite receiver). The receiver unit (from the other end of that UHF remote system) is basically in parallel with the IR receiver of the device I use the UHF remote on.

I'd sooner use an RF unit on 900 Mhz.

PS/2 is rather different. What you probably need to do for those, rather than a two-way communication, is wirelessly transmit the "raw" data from a keyboard matrix or a mouse sensor, and format to PS/2 in the receiver base.
