Tutorial: How to use WiFi IoT D1 Mini Board

The WiFi IoT D1 Mini board is ideal for anyone who wants to explore the world of the Internet of Things (IoT) without investing too much. With it, you can control remote devices, monitor environmental data, and create interactive projects.

What you need

• Arduino IDE installed
• Computer with Windows, Mac or Linux operating system
• USB type A-micro B cable
• WiFi antenna (check the datasheet for specifications)
• WiFi configuration software (check the datasheet for specifications)

Steps

1. Install the Arduino IDE and add the ESP8266 library.
2. Connect the D1 Mini board to the computer via USB.
3. Open the ‘Tools’ menu and select ‘Board’ -> ‘ESP8266 NodeMCU 1.0 (ESP-12E Module)’
4. Select ‘Serial Port’ -> ‘Auto’
5. Verify the connection by downloading a simple example like ‘Blink’.
6. Configure the WiFi network using the configuration software.
7. Load a simple sketch that uses the WiFi connection.
8. Test the connection and data transmission to the WiFi network.

Example code

void setup() {
  Serial.begin(115200);
  WiFi.begin("SSID", "PASSWORD");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("nConnesso!");
}

void loop() {
  // Codice di esempio
}

Mini project

Create a home alarm system that sends email notifications when triggered.
