How to use the infrared port on the back of my netbook to change the channel

Question

I always sit on my couch, watching TV and surfing the net, and I have this idea related to hair to program the infrared port on my laptop to switch the channel. I am programming C # but want to know if anyone else has tried. How to access the port? How can I capture what my universal remote sends to play on TV when I press a button? I could also use this method to program some of my children's toy robots. Maybe this will interest them in programming! Thanks in advance.

Answer 1

I believe that you will see IR as a serial port. You can use it from C # using the System.IO.Ports.SerialPort( msdn ) class .

It could be your starting point.

As for strength, it is strong enough to control your TV (if your living room does not have a width of 10 meters :)). There are programs on PocketPC (universal programmable remotes that capture the IR signal from your TV that you need to configure) that do the same.

Answer 2

You can use the SerialPorts object in .NET. Here is an example project that can give you some ideas: http://code.msdn.microsoft.com/IRDADemo

I studied this in the distant past when IR transceivers were commonplace. Most are not very powerful and will not reach more than 1 meter. It is also difficult to program the infrared port using a serial interface so that it matches the required infrared code. The form that I remember worked only on some TVs. For PDAs, they were more successful, but usually had a weak IR transmitter, so you had to be too close to the TV to be useful.
