How do i check if my arduino wifi is connecting to my other arduino wifi?
Its purpose is to turn on a light when a item is in range of my ultrasonic sensor.
This is my code for the sender
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "Netcomm 3240"; // your network SSID (name)
char key[] = "Ninazoyope"; // your network key
int keyIndex = 0; // your network key Index number
int status = WL_IDLE_STATUS; // the Wifi radio's status
char server[] = "10.0.1.16";
WiFiClient client;
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
}
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WEP network, SSID: ");
Serial.println(ssid);
status = WiFi.begin(ssid, keyIndex, key);
delay(10000);
void loop() {
// check for the presence of wifi:
if (WiFi.status() == WL_CONNECTION_LOST) {
Serial.println("Oops conection lost");
// don't continue:
while (true);
status = WiFi.begin(ssid, keyIndex, key);
}
else
{
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to WEP network, SSID: ");
Serial.println(ssid);
status = WiFi.begin(ssid, keyIndex, key);
// wait 10 seconds for connection:
delay(10000);
}
// once you are connected :
Serial.print("You're connected to the network");
}
}
And here is my code for the receiver
#include <WiFiNINA.h>
#include <utility/wifi_drv.h>
const int redPin = 25;
const int greenPin = 26;
const int bluePin = 27;
char ssid[] = "NetComm 5926";
char pass[] = "xetajamihe";
IPAddress ip(192, 168, 20, 23);
int status = WL_IDLE_STATUS;
WiFiServer server(80);
String readString;
void setup() {
Serial.begin(9600);
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to Network named: ");
Serial.println(ssid);
status = WiFi.begin(ssid, pass);
delay(10000);
}
digitalWrite(LED_BUILTIN, HIGH);
WiFi.config(ip);
server.begin();
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
Serial.print("IP Address: ");
Serial.println(ip);
}
void loop() {
WiFiClient client = server.available();
if (client) {
Serial.println("new client");
while (client.connected())
{
if (client.available())
{
char c = client.read();
if (readString.length() < 100)
{
readString += c;
Serial.write(c);
if (c == '\n') {
//URL PARSE CODE FROM HERE ---
if (readString.indexOf("green") > 0)
{
WiFiDrv::analogWrite(redPin,(0,0));
WiFiDrv::analogWrite(greenPin,(0,0));
WiFiDrv::analogWrite(bluePin,(0,0));
delay(1);
} else if (readString.indexOf("red") > 0) {
WiFiDrv::analogWrite(redPin, random(0,255));
WiFiDrv::analogWrite(greenPin, random(0,255));
WiFiDrv::analogWrite(bluePin, random(0,255));
delay(1);
} else {
Serial.print("PROBLEM: ");
Serial.println(readString);
}
// ------ TO HERE
}
}
}
}
}
}
Thank you
