Programming the Board:
Connecting Sensors and Modules:
Using WiFi and Bluetooth:
WiFi.h and BluetoothSerial.h can be used for programming.Below is an example sketch to connect the Arduino Giga R1 WiFi to a WiFi network:
#include <WiFi.h> // Include the WiFi library
const char* ssid = "Your_SSID"; // Replace with your WiFi network name
const char* password = "Your_Password"; // Replace with your WiFi password
void setup() {
Serial.begin(115200); // Initialize serial communication at 115200 baud
Serial.println("Connecting to WiFi...");
WiFi.begin(ssid, password); // Start WiFi connection
while (WiFi.status() != WL_CONNECTED) {
delay(1000); // Wait for connection
Serial.println("Attempting to connect...");
}
Serial.println("Connected to WiFi!");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP()); // Print the assigned IP address
}
void loop() {
// Add your main code here
}
