wireless technologies

I would like to controll my project in a remote location. Is it possible to wire mother circuit with a very long connection for remote control. I'm planning to substitute the wire with Infrared or RF. What is the best practice concerning todays technology? How do I incorporate infrared transcievers into my project? I'm using PIC16F84A with 4MHz crystal. I'm using PIC Basic. Is there any technical notes explaining how to program infrared transmitter & receiver for remote control? How about RF modules?

Hi emavil,

At present everybody prefers wireless control over
wired control.
Infrared requires line of sight for communication between the modules.
For infra red you have to use IR LED and TSOP 1738.

For wireless you can use laipac RLC/TLC modules which communicate at 433MHz

Essentilly the choice depends on the kind of set up u r using.

I used Tws-Rws 434 kit.It worked fine.
