This means that while it is possible to create your own USB connection software for hardware that doesn’t normally support it (also referred to as bit-banging (2)), this method is still prone to timing errors. ![]() Traffic over the USB port is tied to a very strict timing scheme and is thus rather unforgiving in nature. It needs to identify itself to the host by letting it know what type of device it is (‘I’m a keyboard device’, ‘I’m a printer device’, etc.), what capabilities it has, as well as other assorted things the PC needs to be aware of. To join the USB playground with your device, you need to communicate over the USB port. Since the signaling is standardized and thus OS independent, it doesn’t matter if you’re running Windows, Linux or Mac: they all understand the devices and, if provided with the correct driver, can use them. It consists of a series of hardware standards and a protocol for the plugs and signaling. ![]() USB, or the Universal Serial Bus (1), is in effect the only real way to get hardware devices to talk to your PC. USB is pretty versatile, but it is not a patient beast This project is by no means exhaustive and just intended to give you an idea of what you can do and how easy it is to build these things. There are three distinct areas we’ll have to deal with: the actual button hardware, the software running inside the button and, optionally, the software on your PC to tie it all together. Ha! It’ll be talking to our little device which will mimic a keyboard for us. Your PC is going to detect the pressing of this button just like it would a normal key, but we’re going to fake it: it isn’t really a keyboard the PC is talking to. The button we’re going to construct is very similar however, it’s a keyboard consisting of one key only. Most people have large numbers of these buttons in front of them neatly stuck to a board. How about a nice ominous red button that you can push and make your PC launch your missiles, self-destruct your secret base, or distract the cat?īuttons are usually connected through the USB port. Writing code for websites is all good and well but sometimes you want to do something more, well, tactile. ![]()
