How many serial ports does an Arduino Mega have?
Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin(). The Arduino Mega has three additional serial ports: Serial1 on pins 19 (RX) and 18 (TX), Serial2 on pins 17 (RX) and 16 (TX), Serial3 on pins 15 (RX) and 14 (TX).
How many UART does Arduino Mega have?
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
How do you make serial communication between two Arduino?

What serial protocol does Arduino use?
UART
UART, which stands for Universal Asynchronous Reception and Transmission, is a simple serial communication protocol that allows the host (Arduino) to communicate with serial devices.
What is serial communication programming?
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.
What is serial communication give one example?
Serial communication is a technique used to send data bit by bit using a two-wires i.e. transmitter (sender) and receiver. For example, I want to send an 8-bit binary data 11001110 from the transmitter to the receiver.
