The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name "SoftwareSerial"). It is possible to have multiple software serial ports with speeds up to 115200 bps.Dec 24, 2019

If you could use a slower baud rate, you could keep your debug prints on Serial , and use either AltSoftSerial or NeoSWSerial for your device. But if you have to use 115200, the only reliable choice is Serial . Although AltSoftSerial and SoftwareSerial allow that baud rate, they may not send/receive data correctly.Feb 1, 2017

That facilitates communication between your computer/laptop and the Arduino. While Arduino Uno has a single Hardware Serial, other boards like Mega have multiple. ... Software serial is a library that replicates the hardware serial behavior on other digital pins of the Arduino, using (you guessed it) software.Jul 30, 2021

Serial. begin(9600); passes the value 9600 to the speed parameter. This tells the Arduino to get ready to exchange messages with the Serial Monitor at a data rate of 9600 bits per second. That's 9600 binary ones or zeros per second, and is commonly called a baud rate.

Serial is used for communication between the Arduino board and a computer or other devices. ... All Arduino boards have at least one serial port (also known as a UART or USART): Serial. It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB.

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3. x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.

The UART interface does not use a clock signal to synchronize the transmitter and receiver devices; it transmits data asynchronously. Instead of a clock signal, the transmitter generates a bitstream based on its clock signal while the receiver is using its internal clock signal to sample the incoming data.
