Using a USB (stands for Universal Serial Bus) circuit is the most common method for communicating between devices and computers. People usually used the parallel port or the serial port in the past, but nowadays you may hardly see these ports. They almost non-existent on PCs and laptops, that s because all computers use USB ports.
Is it hard to develop a USB circuit? If you start reading about the USB technology, you might get the feeling that it is really hard to make a circuit with USB, especially you want to make it from scratch. But it doesn’t have to be that hard if you just make use of some tools. You can use a USB chip to make things easier. There are many ways to use a chip, here I m going to mention two of them. You can use the chip in a circuit, because there are only a few components that are necessary to make it work. And the easiest way is to just use a breakout board. Here you can get the chip with all the necessary components to make it work, and what you only need to do is to plug.
