That&#x27;s a neat, different way to do it.  Nowadays I think most people would go straight to building something with Arduino (e.g. <a href="http:&#x2F;&#x2F;apcmag.com&#x2F;arduino-project-usb-foot-operated-mouse-switch.htm&#x2F;" rel="nofollow">http:&#x2F;&#x2F;apcmag.com&#x2F;arduino-project-usb-foot-operated-mouse-sw...</a>), but that&#x27;s not always necessary.
