An Arduino Uno has a single hardware serial port, but serial communication is also possible using software libraries to emulate additional ports (communication channels) to provide connectivity to more than one device. Software serial requires a lot of help from the Arduino controller to send and ...
Serial communication is simplya way to transfer data. The data will be sent sequentially, one bit at a time (1 byte = 8 bits), contrary to parallel communication, where many bits are sent at the same time. UART protocol More specifically, when you use Serial with Arduino and Raspberry Pi...
/*GraphA simple example of communication from the Arduino board to the computer: Thevalue of analog input 0 is sent out the serial port. We call this "serial"communication because the connection appears to both the Arduino and thecomputer as a serial port, even though it may actually use a...
Arduino has an incredibly simple and convenient serial communication library that enables you to transmit data over serial with only two lines of code! The Arduino serial library will be useful throughout these tutorials as it provides an easy way to display the result of your Arduino’s activiti...

SoftwareSerial wifiSerial(2 , 3); Creates the serial interface via software using pins 2 (RX) and 3 (TX). So it can use hardware for the serial communication with the PC (e.g. for debugging purposes) in Arduino models that have only one serial (Ex .: Arduino UNO). ...

Robust Arduino Serialis a simple and robust serial communication protocol. It was designed to make two Arduinos communicate, but can also be useful when you want a computer (e.g. a Raspberry Pi) to communicate with an Arduino. Please read theMedium Articleto have an overview of this protoco...
