Robust Arduino Serial Protocol Robust Arduino Serial is a simple and robust serial communication protocol. After mastering use of the serial protocol to directly control the servo position, they are ready to create interactive projects like mimicking a human hand using the computer, or even wireless Bluetooth or XBee. The key is to add this context data to the byte stream by using a standard serial packet design. 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"). UART protocol Initially Mega is in Transmit mode and Pro Mini is in Receive Mode. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices. Serial ports are used for data communication with computers or other devices. In other words, when you transmit text instead of binary data. All Arduino boards have one or more serial ports that can be UART or USART. It's not a communication protocol, but a physical circuit in a microcontroller (or a stand-alone IC). The main motive of serial communication is to display the data or send the data to Arduino . The Arduino has dedicated pins for I2C, which have built-in pull-up resistors as required by the I2C protocol. They learn to use the serial communication protocol to send information between the computer and the Arduino. SPI, which stands for the serial peripheral interface, is similar to I2C where it is a different form of serial-communications protocol specially designed for microcontrollers to connect. Serial.begin is a function that is used to begin the serial communication and also set the data transfer rate for communication. Used to communicate over short distances at high speed.
