20 Pieces WHITE LED – WHITE super bright standard 5mm LED luminous diodes

Description

What it is

The 5 mm super bright white LEDs are electronic components used for lighting in various projects, such as 3D printing or Arduino circuits. This set contains 20 pieces of white LEDs, ideal for both beginners and experts.

Features

• Brightness level: super bright
• Body diameter: 5 mm
• LED type: WHITE

What it is for

White LEDs can be used to create indicators, RGB lighting by combining with other colors, or simply as a light source in electronic projects. They are compatible with Arduino and ESP for lighting programming.

Tutorial: How to Use Super Bright White LEDs

Super bright white LEDs are ideal for lighting and indicators. Perfect for beginners.

What you need

• White LED
• Arduino
• power supply 5V-12V
• resistor

Steps

1. Check the polarity of the LED: anode (+) long leg, cathode (-) short leg.
2. Connect the anode to a digital pin on the Arduino and the cathode to a resistor.
3. Connect the other end of the resistor to ground (GND).
4. Check the datasheet for the LED’s operating current to choose the right resistor.
5. Write an Arduino sketch to cyclically turn the LED on and off.

Example code

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

void loop() {
  digitalWrite(13, HIGH);   
  delay(500);               
  digitalWrite(13, LOW);    
  delay(500);               
}

Mini project

Create an RGB lighting using three LEDs of different colors.

Common mistakes

• Do not check the polarity of the LED.
• Use a resistor that is too small or too large.
• Connect the LED without a resistor.

Recommended accessories

• Variable resistors
• RGB modules
• Arduino Uno

Frequently asked questions
