Summary of Arduino Serial Communication Code
This article explains how to use Arduino's serial communication feature to send output to a computer via USB. By connecting an Arduino to a computer with a USB A-B cable and uploading a simple code, users can see text output in the Arduino Serial Monitor. The example code initializes serial communication at 9600 baud and periodically sends text messages every 3 seconds. This basic setup helps users monitor Arduino data like status updates or sensor readings in real time.
Parts used in the Arduino Serial Communication Project:
- USB cable A-B
- Arduino board
Arduino can send output through serial communication to your computer over USB. The output can be anything such as status, text, sensor reading, value, number etc. You can view the status output by clicking Serial Monitor button at Arduino Environment software.
Instruction;
1) Connect your arduino to your computer using USB cable A plug to B plug.

}
void loop() {
Serial.println("output text send through serial print");
Serial.println("delay 3 seconds");
delay(3000);
}Serial.begin(9600);
Instruct arduino to start serial communication with 9600 bits of data per second.
