What is Arduino serial communication

What is Arduino Serial Communication?

We will talk about the third type of output that is serial communication or serial output.

Serial communication is used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several ports.

Arduino dedicates pin 0 for receiving information and pin 1 for transferring information. What is the baud rate in communication? The baud rate is the rate at which data is transmitted in a communication channel. In the serial port context, "9600 baud" means that the serial port can transfer a maximum of 9600 bits per second.

In the video, how to use serial communication in coding is explained. Without hardware, you can test your output of the program on the serial monitor. You can check whether your program is working correctly or not. To protect your hardware, first, run your program on the serial monitor.

Till now, we have learned three types of output: Digital, analog in terms of PWM and serial. In the next video, we will see what is Digital Input.


The Arduino serial communication is a way of communicating with Arduino board using the C++ language. This communication method uses software libraries to send and receive data from the computer to the Arduino board.

  • Arduino is an open-source electronics platform that allows you to build interactive devices and prototypes without the need for expensive tools or complicated programming languages.
  • The most common way to use Arduino is to communicate with your device through a physical wire. However, it can also be used as a network interface. In this case, you would connect your device to the Arduino’s Ethernet port and then use the Arduino IDE to program it.

Arduino offers better performance than serial communication interfaces like RS232 and USB. It has a much lower power consumption than RS232 as well as USB. It also offers better flexibility in terms of the amount of data that can be transmitted at once and the speed at which it can transmit data.

Serial communication is a way to communicate between two devices. It is a one-way process, meaning that only one device can send data at a time. The Arduino Serial Library provides the Arduino with the ability to communicate using serial communication.

  • IoT Arduino is a platform that helps the small businesses and individuals to create IoT projects. It can be used for a variety of purposes like monitoring and controlling the temperature, humidity, lighting, etc.
  • The benefits of using IoT Arduino are that it provides a flexible solution for your project needs as well as provides an easy way to connect with other devices or systems.
