Tutorial: How to Use DC12V Solenoid Electromagnets

This linear electromagnet with integrated spring return is ideal for projects that require mechanical movement controlled by a circuit. It is perfect for both beginners and expert creators.

What you need

• Arduino or microcontroller
• network power supply or battery
• connection cables

Steps

1. Connect the positive and negative leads of the electromagnet to the microcontroller.
2. Check the operating voltage (12V) and maximum current (2A).
3. Write an Arduino sketch to control the solenoid via a relay or MOSFET.
4. Test the connection with Arduino, turning the solenoid on and off.
5. If necessary, add a fuse protection between the power supply and the solenoid.
6. Check the stability of the mechanism when the solenoid is active.
7. Try to integrate a sensor to control the state of the electromagnet.
8. End.

Example code

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

void loop() {
  digitalWrite(relè_pin, HIGH); // Attiva il solenoide
  delay(1000);
  digitalWrite(relè_pin, LOW); // Disattiva il solenoide
  delay(500);
}

Mini project

Build an automatic closing system for drawers or doors that open and close with the electromagnet.

Common mistakes

• Connect the solenoid directly to the microcontroller without protection.
• Do not check the voltage and maximum current before connection.
• Use a relay or MOSFET not suitable for the power of the electromagnet.

Recommended accessories

• Relay for Arduino
• N-Channel MOSFET
• Position sensor
• 12V power supply
