What are some examples of communication methods for Arduino?

Arduino can communicate using various methods like Serial, I2C, SPI, and Bluetooth. Would you like details on a specific method?

Can you explain how Serial communication works?

Sure! Serial communication sends data one bit at a time over a single wire. It's commonly used for debugging and communication with computers.

What about I2C? How does that differ from Serial?

I2C allows multiple devices to communicate over two wires (SDA for data and SCL for clock). It's more efficient for connecting multiple devices compared to Serial.

Can you give me a simple code example for I2C communication?

Absolutely! Here's a basic example:

#include <Wire.h>

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

void loop() {
  Wire.requestFrom(8, 6);
  while (Wire.available()) {
    char c = Wire.read();
    Serial.print(c);
  }
}

This code requests data from a device with address 8.
