What are the basics of serial communication in Arduino?

Serial communication in Arduino allows for data exchange between the Arduino and other devices, like computers. It uses a simple protocol to send and receive data one bit at a time.

How do I set up serial communication in my Arduino code?

To set up serial communication, you need to initialize the serial port in your setup() function using Serial.begin(baudRate);, where baudRate is typically 9600.

What is the difference between Serial.print() and Serial.println()?

Serial.print() sends data without a newline at the end, while Serial.println() sends data followed by a newline, which helps in formatting the output.

Can I use serial communication to control devices?

Yes, you can use serial communication to send commands from your computer to the Arduino, allowing you to control devices connected to it.
