The ESP-14 module is ideal for creating IoT (Internet of Things) and wireless sensor projects. It can be used to transmit data over the network, remotely control devices, or create monitoring applications. It is compatible with Arduino and other microcontrollers that support serial communication.

Tutorial: How to Use ESP-14 Wi-Fi Module

The ESP-14 Wi-Fi module allows adding wireless connectivity to any Arduino project. Ideal for beginners and makers who want to transmit data over the network without complications.

What you need

• Arduino Uno or compatible
• USB Type B cable
• 5V power supply

Steps

1. Connect the Arduino board to the computer via USB cable.
2. Connect the VCC and GND pins of the ESP-14 module to the corresponding pins on the Arduino board.
3. Use the TX pin of the ESP-14 module to connect to the RX pin of Arduino, and the RX pin of the module to the TX pin of Arduino (using a 1kΩ pull-up resistor between the two TX pins).
4. Install the ESP8266 library in the Arduino IDE.
5. Upload the following sketch to the ESP-14 module via the Arduino board.
6. Verify the Wi-Fi connection and send data from the serial console.

Example code

void setup() {
  Serial.begin(9600);
  // Configurazione Wi-Fi (verifica sul datasheet per i dettagli)
}

void loop() {
  if(Serial.available()) {
    String message = Serial.readString();
    // Trasmetti il messaggio tramite Wi-Fi
  }
}

Mini project

Create a wireless temperature sensor that sends data via Wi-Fi to a serial console.

Common mistakes

• Do not verify the correct installation of the ESP8266 library.
• Enter incorrect Wi-Fi credentials in the code.
• Omit the connection between TX and RX with a pull-up resistor.
• Ignore the importance of proper power supply for the ESP-14 module.

Recommended accessories

• 1kΩ resistor
• Wi-Fi antenna for ESP8266
• DHT11 module or similar to measure temperature
