Tutorial: How to use 4-way Toggle Switch 2.54mm

The 4-way toggle switch 2.54mm is a fundamental component for electronic projects that require selection between multiple options. Perfect for beginners and intermediate makers, it allows for simple and reliable management of electrical flow.

What you need

• Arduino
• Connection wire
• Test pin

Steps

1. Install the switch on a breadboard.
2. Connect the switch pins to the Arduino digital pins using connection wires.
3. Write and upload the Arduino sketch to test the switch.
4. Verify that the switch works correctly by changing the lever positions.
5. If necessary, adjust the connections to ensure a stable connection.

Example code

void setup() {
  pinMode(2, INPUT);
  pinMode(3, INPUT);
  pinMode(4, INPUT);
  pinMode(5, INPUT);
}

void loop() {
  int val = digitalRead(2);
  if (val == HIGH) {
    Serial.println("Posizione 1");
  }
  val = digitalRead(3);
  if (val == HIGH) {
    Serial.println("Posizione 2");
  }
  val = digitalRead(4);
  if (val == HIGH) {
    Serial.println("Posizione 3");
  }
  val = digitalRead(5);
  if (val == HIGH) {
    Serial.println("Posizione 4");
  }
}

Mini project

Create a small prototype that changes the LED brightness based on the switch position. Use the Arduino digital pins to control the LED PWM output value.

Common mistakes

• Unstable or intermittent connections.
• Default switch positions incorrect.
• Pins not configured correctly in Arduino.
• Error reading the logical value of the switch.

Recommended accessories

• Breadboard
• Arduino Uno
• Connecting cables
• LED

Frequently asked questions

Which pins should I use?
