Tutorial: How to Use HL-5030 Adjustable Rotary Lever

The HL-5030 rotary lever is a momentary contact switch used for temporary actions in electronic circuits. Ideal for home automation projects, prototypes, and control systems.

What you need

• Arduino Uno
• Connectors
• Insulated Wire

Steps

1. Install the HL-5030 rotary lever on a stable mounting.
2. Connect the insulated wire to the contacts of the rotary lever (check the datasheet).
3. Connect the opposite end of the wire to the input pin of the Arduino (check the datasheet).
4. Download and upload the provided Arduino sketch.
5. Press the lever to test the functionality.

Example code

void setup() {
  pinMode(2, INPUT);
}

void loop() {
  if (digitalRead(2) == HIGH) {
    Serial.println("Pulsante premuto");
  }
}

Mini project

Create a home security system that sends a notification when the lever is pressed.

Common mistakes

• Incorrect cable connections
• Incorrect Arduino pin configuration
• Button does not work due to insufficient insulation

Recommended accessories

• Arduino Uno R3
• Prototype connections
• 20cm insulated cable
