What are some examples of serial communication with Arduino?

Serial communication allows Arduino to communicate with other devices. Common examples include sending data to a computer or another microcontroller.

Can you give me a simple code example for serial communication?

Sure! Here's a basic example:

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("Hello, World!");
  delay(1000);
}

This code sends "Hello, World!" to the serial monitor every second.

How do I read data from the serial port?

You can read data using Serial.read() or Serial.readString(). For example:

if (Serial.available()) {
  String data = Serial.readString();
  Serial.println(data);
}

What are some common issues with serial communication?

Common issues include baud rate mismatches, incorrect wiring, and buffer overflows. Always check your connections and settings.
