Tutorial: How to Use the DC5-80V Relay Module for ESP8266

This relay module allows control of power supplies with voltages from 5 to 80V using an ESP8266 microcontroller. Ideal for projects requiring remote control of electrical devices.

What you need

• ESP8266
• Arduino IDE
• USB Power Supply
• Jumper Wires

Steps

1. Step 1: Connect VCC to pin 3V3 of the ESP8266
2. Step 2: Connect GND to one of the GND pins of the ESP8266
3. Step 3: Connect IN to one of the digital pins of the ESP8266 (for example D1)
4. Step 4: Check the operating voltage of the device to be controlled and connect COM to the device
5. Step 5: Connect NC or NO to the device according to the project requirements
6. Step 6: Open Arduino IDE and upload a sketch that activates/deactivates the relay (see code)
7. Step 7: Verify the ESP8266 connection with software like Tera Term or PuTTY
8. Step 8: Test the relay module by pressing the keys to activate/deactivate the output

Example code

void setup() {
  pinMode(1, OUTPUT);
}

void loop() {
  digitalWrite(1, HIGH); // Attiva il relè
  delay(2000);
  digitalWrite(1, LOW); // Disattiva il relè
  delay(2000);
}

Mini project
