Unfortunately, the uno only has one, which would be serial.begin, as you refer to it. To simplify, pin 0 and 1 is the native serial port on the uno. You can use it with no problems, however you'll need to disconnect anything attached to it when you program your auno (these pins are shared by the serial input to the arduino from the pc). Arduino Uno – Programming With A Serial Port 1. Connect jumper wires to pins 2,3,4, and 5 of a DB9-F serial port connector. Remove RN4 and C5 which connect the ATMEGA16U2 (programmer) to the ATMEGA328P (Arduino). Connect an RS232 converter IC (I used a MAX202) between the DB9-F and the. Arduino Serial Communication. When coming to Arduino, the communication between Arduino UNO (or any other board) and computer is serial communication. The main purpose of this serial communication is to transfer the sketch from computer to Arduino, send information to computer etc. The most common type of serial communication protocol is UART.
Serial Communication between ESP2866-12 (NODE-MCU) and Arduino to increase the number of analog pins as my primary work.

About this project
This project is all about serial communication between ESP8266-12(NODE-MCU) and Arduino. As we know ESP-12 have one analog pin where we can connect our analog sensor, But what else if we need more than one analog pin to connect more analog sensor and again if you want to send data to server like adafruit.io or your own server.
A video tutorial to follow, Hope it helps.
