How to Use StrobeIT Anti-Collision Drone Light: Examples, Pinouts, and Specs

The StrobeIT Anti-Collision Drone Light by Teravolt (Part ID: PWM LED) is a high-visibility LED light designed to enhance drone safety during flight. This component is particularly useful in low-light or nighttime conditions, where visibility is critical. It features multiple flashing modes to alert other airspace users, reducing the risk of mid-air collisions. The compact design and efficient power consumption make it ideal for drones of all sizes.

• Enhancing drone visibility during nighttime or low-light operations.
• Compliance with aviation safety regulations for unmanned aerial vehicles (UAVs).
• Use in search-and-rescue drones to improve visibility in challenging environments.
• Recreational drone flights to ensure safety in shared airspace.

1. Power Connection: Connect the VCC pin to a power source within the operating voltage range (3.7V - 6.0V). Connect the GND pin to the ground of the power source.
2. PWM Signal: Use the PWM pin to control the flashing mode. A PWM signal with varying duty cycles can be used to switch between steady, slow flash, and fast flash modes.
3. Mounting: Secure the StrobeIT light to your drone using adhesive or screws, ensuring it is visible from all angles.

• Ensure the power source provides a stable voltage within the specified range to avoid damaging the component.
• Use heat-resistant adhesive or mounting hardware to prevent detachment during operation.
• Avoid direct exposure to water or moisture, as the component is not waterproof.
• When connecting to a microcontroller (e.g., Arduino UNO), use a resistor if necessary to limit current to the PWM pin.

The following code demonstrates how to control the StrobeIT Anti-Collision Drone Light using an Arduino UNO. The code cycles through steady, slow flash, and fast flash modes.

// Define the PWM pin connected to the StrobeIT light
const int pwmPin = 9;

void setup() {
  pinMode(pwmPin, OUTPUT); // Set the PWM pin as an output
}

void loop() {
  // Steady mode: 100% duty cycle
  analogWrite(pwmPin, 255); // Full brightness
  delay(5000); // Stay in steady mode for 5 seconds

  // Slow flash mode: 50% duty cycle
  for (int i = 0; i < 10; i++) {
    analogWrite(pwmPin, 255); // Turn on
    delay(500); // On for 500ms
    analogWrite(pwmPin, 0);   // Turn off
    delay(500); // Off for 500ms
  }

  // Fast flash mode: 25% duty cycle
  for (int i = 0; i < 20; i++) {
    analogWrite(pwmPin, 255); // Turn on
    delay(100); // On for 100ms
    analogWrite(pwmPin, 0);   // Turn off
    delay(100); // Off for 100ms
  }
}

1. The LED does not turn on:

   • Ensure the power source is within the operating voltage range (3.7V - 6.0V).
   • Check all connections, especially the VCC and GND pins.
   • Verify that the PWM signal is being sent correctly from the microcontroller.

2. Flashing modes do not change:

   • Confirm that the PWM signal is configured correctly. Use an oscilloscope or multimeter to check the signal.
   • Ensure the PWM pin is connected securely to the microcontroller.

3. The light is dim or flickering:

   • Check the power source for stability. A low or fluctuating voltage can cause dimming or flickering.
   • Inspect the wiring for loose connections or damaged cables.

Q: Can I use the StrobeIT light with a 12V power source?
A: No, the maximum operating voltage is 6.0V. Using a higher voltage may damage the component.

Q: Is the StrobeIT light waterproof?
A: No, the component is not waterproof. Avoid exposing it to water or moisture.

Q: Can I change the default LED color?
A: The default LED color is white. Customization may require replacing the LED, which is not recommended as it may void the warranty.

Q: How do I mount the light on my drone?
A: Use heat-resistant adhesive or screws to secure the light. Ensure it is mounted in a location visible from all angles.
