After that, it does the same on the second virtual port (portTwo). The board listens on one virtual port (portOne) until it has read all available data. A number of libraries come installed with the IDE. To use a library in a sketch, select it from Sketch > Import Library. working with hardware or manipulating data. Libraries provide extra functionality for use in sketches, e.g. In the example below, digital pins 8 and 10 on your Arduino board are used as virtual RX serial lines. The Arduino environment can be extended through the use of libraries, just like most programming platforms. This can be extremely helpful when the need arises to communicate with two serial enabled devices, or to talk with just one device while leaving the main serial port open for debugging purpose. Arduino boards have built in support for serial communication on pins 0 and 1, but what if you need more serial ports? The SoftwareSerial Library has been developed to allow serial communication to take place on the other digital pins of your boards, using software to replicate the functionality of the hardwired RX and TX lines.
