Tutorial: How to use Electric Lock LY-03 DC12V

The electric lock LY-03 is an ideal device for protecting lockers or drawers. This steel solenoid can be easily integrated into home or industrial security projects.

What you need

• Arduino Uno
• 12V Power Supply
• Relay Module
• Antenna Cable

Steps

1. Connect the electric lock to the 12V power supply.
2. Connect the relay module to the Arduino Uno to control the lock’s power.
3. Write the Arduino sketch that activates/deactivates the relay based on received commands.
4. Verify the correct integration of the system by connecting a button to the circuit to test the open/close function.

Example code

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

void loop() {
  if (digitalRead(BUTTON_PIN) == HIGH) {
    digitalWrite(RELAY_PIN, HIGH); // Attiva il solenoide per aprire la serratura
  } else {
    digitalWrite(RELAY_PIN, LOW); // Disattiva il solenoide per chiudere la serratura
  }
}

Mini project

Create a security system for your room’s locker that opens with a simple button press.

Common mistakes

• Do not properly verify the electrical connection before use.
• Use voltages other than 12V without an appropriate converter.
• Omit protection against induced currents when deactivating the solenoid.

Recommended accessories

• Relay Module
• Arduino Power Supply
• Momentary Push Button
• Resistor
