The Serial. It is the data, which is already stored and arrived in the serial buffer. The serial buffer in Arduino holds the 64 bytes.

Arduino serial available is a function that you use in conjunction with the following functions:. Before you can use Serial. You then use the function Serial. If data is available then you call Serial. For example, if you have sent five characters over the serial port from the PC and call Serial. You can then use Serial. Each time you read out a byte from the buffer the value returned by Serial.

Most people stumble across the Arduino Serial. Serial communication is the process of sending one bit of data at a time, sequentially, from one place to another. For example, using serial data, you could send data from your Raspberry Pi to a connected Arduino, or vice versa. USB is one of the most common ways to transmit serial communication — hence the name Universal Serial Bus. An Arduino library is basically a bunch of code that has been bundled together to make your life easier. A good way to do that would be to set up a drawer in your barber shop to hold all your hair-cutting tools in one place. Every time a customer walks into your fine establishment for a haircut, all you need to do is open your drawer, and everything you need is right there in easy reach. And, of course, you may have a whole bunch of similar drawers. One might be for dying hair. Another might be for polishing the heads of bald folks to a high glossy shine. Arduino libraries bring together a bunch of software functions that help you with specific tasks.
