What you need

• Arduino Uno
• Resistor
• Connecting Wire
• Breadboard
• Connections

Steps

1. Check the operating voltage and maximum current of the LED on the datasheet.
2. Connect the anode (longer pin) of the LED to the Arduino output pin through a resistor.
3. Connect the cathode (shorter pin) of the LED to the Arduino ground (GND).
4. Write a sketch to turn on the LED.
5. Verify the operation of the LED.
6. If necessary, adjust the resistor to optimize the operation.
7. Repeat steps 1-5 for each LED in the kit.
8. Try combining multiple LEDs to increase the brightness of the UV light.

Example code

void setup() {
  pinMode(13, OUTPUT);
}

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

Mini project

Create a portable blacklight lamp: connect a set of UV LEDs to the USB torch power circuit. Use a switch to control the UV light.

Common mistakes
