Description

What is the UV LED Kit 365-370nm 0.2W SMD – 4 Pieces? This kit includes four ultraviolet (UV) LEDs with a wavelength of 365 to 370 nanometres, each with a power rating of 0.2 watts and using Surface Mount Device (SMD) technology for compact mounting. Features: 4 UV SMD LEDs Wavelength: 365-370nm Power: 0.2W per LED SKU: ARD0012204 Price: €1.97 What is it used for? These UV LEDs are perfect for projects requiring ultraviolet light, such as security applications, material research and development of fluorescent materials. They can be used to create home alarm systems that use fluorescent markers on valuable items or for 3D printing applications requiring UV curing. Tutorial: How to Use the UV LED Kit 365-370nm 0.2W SMD This kit of four UV LEDs with a wavelength of 365-370nm is ideal for projects that require ultraviolet light, such as security systems and material research involving fluorescent materials. What you need: Arduino Uno or compatible power supply (5V) resistors connecting wires 3D printer (optional for housing) multimeter (optional for testing) Steps Check the operating voltage and maximum current of the LED on the datasheet. Connect a resistor between an Arduino output pin and the cathode of the LED. Connect the LED to the 5V power supply using a connecting wire. Write an Arduino sketch to control the LED. Test the LED with a multimeter to ensure proper operation. If necessary, print a 3D housing for the LED and connections. Repeat steps 1-5 for all LEDs in the kit. Use the UV LEDs to explore fluorescent materials or security 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 uses UV LEDs to illuminate fluorescent markers on valuable items. If the item is removed, the UV light will activate to signal an alarm. Common mistakes Using an inadequate resistor which can damage the LED. Not checking the operating voltage of the LED. Connecting the LED directly to 5V without a resistor. Not testing the LED before using it in a project.
