Tutorial: How to use Delay Timer Relay Module 1 Channel

The delay timer relay module is a useful component for controlling electrical devices through a microcontroller. Ideal for beginners and makers who want to automate simple domestic or industrial processes.

What you need

• Arduino Uno
• USB cable for Arduino
• 9V battery
• Relay
• Connectors

Steps

1. Connect the relay module to the control pin of the Arduino
2. Check the module’s supply voltage (check in the datasheet)
3. Write the Arduino sketch to adjust the delay time
4. Upload the sketch to the microcontroller
5. Test the module with a simple electrical device
6. Adjust the delay time according to the requirements
7. Verify the system stability
8. Document the operation and results

Example code

const int relayPin = 12; // Pin di controllo del relè

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

void loop() {
  digitalWrite(relayPin, HIGH); // Attiva il relè
  delay(5000); // Attende 5 secondi
  digitalWrite(relayPin, LOW); // Disattiva il relè
  delay(5000); // Attende 5 secondi
}

Mini project

Create an automatic lighting system that turns on and off at regular intervals. Use the relay module to control a lamp and adjust the delay time with the Arduino sketch.

Common mistakes

• Do not check the module’s supply voltage
• Do not connect the relay correctly to the microcontroller
• Do not test the module before using it in a project
