UV LED SMD Kit – 380-385nm – 4 Pieces

Description

What is the UV LED SMD Kit? This kit contains four high-performance UV LEDs designed for applications requiring ultraviolet light. These LEDs are particularly useful for 3D printing, trace revelation, and other uses that require UV light.

Features:
– 4 pieces of UV SMD LEDs
– Wavelength: 380-385nm

How to use the UV LED SMD Kit – 4 Pieces?
This kit is perfect for projects requiring ultraviolet light. Useful for working with materials that react to UV, such as certain inks or paints.

What do you need?
– UV LED SMD Kit – 4 pieces
– 390 Ohm resistor (check the datasheet)
– Arduino microcontroller
– USB cable

Steps:
1. Mount the Arduino microcontroller on a board.
2. Connect to your computer with the USB cable.
3. Upload the following code to the microcontroller.
4. Connect one UV LED to digital pin 13 and the resistor.
5. Turn on the UV LED using the code.
6. Check that the LED emits ultraviolet light.
7. Disconnect the microcontroller and turn off the LED.
8. Repeat steps 4-7 with the remaining three UV LEDs.

Example Code:
“`void setup() {
pinMode(13, OUTPUT);}
void loop() {
digitalWrite(13, HIGH); delay(2000);
digitalWrite(13, LOW); delay(2000);
}“`

Mini-project: Create a UV indicator that lights up when exposed to ultraviolet light.

Common mistakes:
– Do not connect the LED directly to the microcontroller without a resistor.
– Ensure the microcontroller is properly powered.
– Verify the correct pin for the LED.
– Check if the UV LED emits ultraviolet light.

Recommended accessories:
– Arduino microcontroller
– 390 Ohm resistor
– USB cable
– Microcontroller holder

FAQ:
How can I verify that the UV LED emits ultraviolet light?
Use a UV detector or observe the reaction of materials sensitive to UV.
Can I use the UV LED with other microcontrollers?
Yes, but check pin and power compatibility.
Does the UV LED emit visible white light?
No, it emits invisible ultraviolet light.
