Hi,
I just registered on Blynk and I’m trying to register using an arduino uno R3 and a wifi shield R3. Using the given code with the arduino online code editor I get a “wifi not found” error. However I am sure of the ssid and the pass I’m using.
The code :

/* Fill-in information from Blynk Device Info here */
#define BLYNK_TEMPLATE_ID "TMPL5-c8n2yGM"

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "STRONG_75c9_2.4GHz"; // your network SSID (name)
char pass[] = "*******"; // your network password
BlynkTimer timer;
//WiFiServer server(50000);
// This function is called every time the Virtual Pin 0 state changes
BLYNK_WRITE(V0)
{
// Set incoming value from pin V0 to a variable
int value = param.asInt();
// Update state
Blynk.virtualWrite(V1, value);
}
// This function is called every time the device is connected to the Blynk.Cloud
BLYNK_CONNECTED()
{
// Change Web Link Button message to "Congratulations!"
Blynk.setProperty(V3, "offImageUrl", "*****://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations.png");
Blynk.setProperty(V3, "onImageUrl", "*****://static-image.nyc3.cdn.digitaloceanspaces.com/general/fte/congratulations_pressed.png");
Blynk.setProperty(V3, "url", "*****://docs.blynk.io/en/getting-started/what-do-i-need-to-blynk/how-quickstart-device-was-made");
}
// This function sends Arduino's uptime every second to Virtual Pin 2.
void myTimerEvent()
{
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V2, millis() / 1000);
}
void setup()
{
// Debug console
Serial.begin(115200);
Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass);
// You can also specify server:
//Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass, "blynk.cloud", 80);
//Blynk.begin(BLYNK_AUTH_TOKEN, ssid, pass, IPAddress(192,168,1,100), 8080);
// Setup a function to be called every second
timer.setInterval(1000L, myTimerEvent);
}
void loop()
{
Blynk.run();
timer.run();
// You can inject your own code or combine it with other sketches.
// Check other examples on how to communicate with Blynk. Remember
// to avoid delay() function!
}
