Can sockets be used to communicate between two Raspberry Pis?

There a loads of protocols. You can use tcp/udp or higher level protocols like http. can’t you connect the 2 raspberry with ethernet or with a switch, and then get the ip of the 2 raspberry, and in your programm you use standard sockets.

Which serial communication method is used in Raspberry Pi?

Raspberry Pi can communicate serial data with other devices using some of the common serial communication protocols, such as UART, I2C, SPI, and USB. There are two UART ports/interfaces, two I2C ports (one for HATS and other for external devices), two SPI ports, and four USB ports on RPi 3B/4B.

How does Raspberry Pi connect to each other?

Plug in your wifi dongle to a USB port on the Raspberry Pi. Connect your ethernet cable to your computer and to the Raspberry Pi. Plug in the wall power adapter into the Raspberry Pi, and then plug it into the wall to turn the power on. Once the power is connected to the wall, the Raspberry Pi will be on.

More precisely, Raspberry A receives an input to GPIO. A python code read the status of GPIO and sends an input to raspberry B that is read by an other python code. Raspberry B python code sends back to Raspberry A a message for doing something.

How does a Raspberry Pi communicate with an Arduino?

Serial Peripheral Interface (SPI) is a 4-wire (MOSI (Master Output Slave Input), MISO (Master Input Slave Output), SS (Slave Select), and SCLK (Serial Clock)), full-duplex serial communication protocol. It uses the master-slave configuration to communicate on a preconfigured frequency at very high speeds.
