4 Pieces 365-370nm UV LEDs

Description

Our 365-370nm UV LEDs are small lighting devices that emit ultraviolet light within a specific wavelength range. These LEDs are ideal for Arduino projects and applications requiring the detection or recognition of hidden marks. Features: Wavelength: 365-370nm

What can they be used for: UV LEDs can be used to create security systems that emit a UV signal when activated. They are also perfect for illuminating hidden marks on objects or documents.

Tutorial: How to use 365-370nm UV LEDs
These UV LEDs are ideal for special lighting projects, hidden mark recognition, and security. They are perfect for beginners exploring the UV world.

What you need: Arduino Uno, jumper wires, resistor (check datasheet), breadboard
Steps: Connect the anode of the LED to the Arduino output pin. Connect the resistor between the pin and the positive battery or power supply. Connect the cathode of the LED to ground via a jumper wire. Write the Arduino sketch to turn on the LED. Verify that the LED turns on correctly. If necessary, adjust the resistor based on the operating voltage. Example code: void setup() { pinMode(13, OUTPUT); } void loop() { digitalWrite(13, HIGH); // turn on the LED delay(1000); digitalWrite(13, LOW); // turn off the LED delay(1000); } Mini-project: Create a security system that emits a UV signal when activated. You can use these LEDs to illuminate hidden marks on objects.

Common errors: Using an inappropriate resistor. Incorrectly connecting the LED to ground. Ignoring the operating voltage of the LED. Not verifying if the LED emits UV light.

Recommended accessories: Variable resistors, Arduino Nano, RGB LEDs, LiPo battery
