Esbrinant si la «Nano 33 IoT» fa connexió a la wifi local
Agafem la nostra «Nano 33 IoT» connectada a l'ordinador amb el cable USB i anem a provar el següent programa tret de la pàgina d'Arduino aquesta.
Anomena i desa aquest programa amb el nom Nano_Wifi dins la carpeta Arduino del teu ordinador, no el carregues encara al Nano, et cal crear una altra subprograma amb les contrasenyes de la wifi.
#include <WiFiNINA.h>
#include "arduino_secrets.h"
//please enter your sensitive data in the Secret tab
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // your network password (use for WPA, or use as key for WEP)
int status = WL_IDLE_STATUS; // the Wi-Fi radio's status
int ledState = LOW; //ledState used to set the LED
unsigned long previousMillisInfo = 0; //will store last time Wi-Fi information was updated
unsigned long previousMillisLED = 0; // will store the last time LED was updated
const int intervalInfo = 5000; // interval at which to update the board information
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial);
// set the LED as output
pinMode(LED_BUILTIN, OUTPUT);
// attempt to connect to Wi-Fi network:
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to network: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
delay(10000);
}
// you're connected now, so print out the data:
Serial.println("You're connected to the network");
Serial.println("---------------------------------------");
}
void loop() {
unsigned long currentMillisInfo = millis();
// check if the time after the last update is bigger the interval
if (currentMillisInfo - previousMillisInfo >= intervalInfo) {
previousMillisInfo = currentMillisInfo;
Serial.println("Board Information:");
// print your board's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print your network's SSID:
Serial.println();
Serial.println("Network Information:");
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.println(rssi);
Serial.println("---------------------------------------");
}
unsigned long currentMillisLED = millis();
// measure the signal strength and convert it into a time interval
int intervalLED = WiFi.RSSI() * -10;
// check if the time after the last blink is bigger the interval
if (currentMillisLED - previousMillisLED >= intervalLED) {
previousMillisLED = currentMillisLED;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW) {
ledState = HIGH;
} else {
ledState = LOW;
}
// set the LED with the ledState of the variable:
digitalWrite(LED_BUILTIN, ledState);
}
}

Crea dins la carpeta Nano_Wifi un fitxer que es diga arduino_secrets.h amb les dues ratlles següents de contingut:
#define SECRET_SSID "El teu nom de la xarxa o SSID"
#define SECRET_PASS "La contrasenya de la wifi teua"
