Tutorial: How to use UV 395-400nm 0.5W SMD LED Kit

This UV LED kit is ideal for projects requiring ultraviolet light, such as security, photography, and fluorescent material research and development. It is perfect for makers and students who want to explore UV light in electronic projects.

What you need

• Arduino Uno
• Resistors
• Prototype wire
• 3D Printing (optional for the LED support)

Steps

1. 1. Identify the LED pins (anode and cathode).
2. 2. Connect the anode of the LED to an Arduino output pin and the cathode to a resistor.
3. 3. Connect the other end of the resistor to GND.
4. 4. Upload the Arduino code to turn on the LED.
5. 5. Check the UV illumination using a fluorescent material.
6. 6. (Optional) Design a 3D printed support for the UV LED for more complex projects.

Example code

void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); delay(1000); digitalWrite(13, LOW); delay(1000); }

Mini project

Create a home security system that activates an alarm when abnormal UV light is detected.

Common mistakes

• Using a resistor that is too small.
• Do not verify the correct connection between anode and cathode.
• Use a non-fluorescent material to test the UV LED.
• Do not use eye protection during the UV light experiment.

Recommended accessories

• Variable resistors
• Eye protection modules
• Safety kit
• 3D printing kit for LED mounts
