网上的PC遥控软件还真不少，从电路的简单性和软件的易用性来考虑，我选择了一款名为“PC红外遥控器”的软件(在天极下载)。它虽然是个共享软件，但没有任何的功能限制。现在的版本是1.0B，同时还自带了一个简单的红外接收电路图，很适合我们自己动手来做。从网上下载的“PC红外遥控器”是一个RAR的自解压包，只有278KB，解压后，双击其中的IRCtrl.exe，它会以一个遥控器图标的形式放在系统的托盘里。单击它，就可以打开“PC红外遥控器”的设置界面。具体的设置方法后面再讲，这里我们要用的就是它设置界面里的电路图-online PC remote control software really many, from the simple circuit and software to consider the ease of use, I chose the one called "PC infrared remote control" software (downloaded Inc.). Although it is sharing software, but no functional limitations. Now is the version 1.0B, and also own a simple infrared receiver circuit. very suitable for us to do it ourselves. Downloaded from the Internet "PC infrared remote control" is a self-extracting RAR package, only 278KB, unpacked, double-click the IRCtrl.exe, it will be a remote control device in the form of icon on the system tray. Click it, it can open up "PC infrared remote control" set interface. Specific configuration back repeatedly, here we have to use the interface is that it's set up circuit
