Product Description (Detailed):
Illuminate your electronic projects with the vibrant 5mm Red LED DIP – Bright Diffused Light Emitting Diode, a fundamental component for any maker or engineer. This through-hole, DIP (Dual In-line Package) LED is renowned for its ease of use and consistent, broad illumination, thanks to its diffused lens. Unlike clear lenses that produce a focused beam, the diffused lens ensures a wide viewing angle, making it perfect for status indicators, decorative lighting, and panel illumination where even light distribution is key. Operating typically with a forward voltage (Vf) of around 1.8V to 2.2V and a forward current (If) of 20mA, these LEDs are easily integrated into circuits with a simple current-limiting resistor to prevent burnout. Their standard 5mm diameter makes them compatible with breadboards, perfboards, and custom PCBs. Emitting a clear, bright red light, these light-emitting diodes are essential for visual feedback in Arduino projects, warning indicators, toy electronics, and various prototyping applications. With their robust build and reliable performance, these bright red LEDs provide an excellent balance of visibility and power efficiency, serving as an indispensable visual component in countless electronic designs.
This 5mm Red LED is a widely used diffused light-emitting diode that provides a clear, visible glow for signaling and status indication. Its frosted lens design spreads the light evenly, making it ideal for educational electronics, indicator circuits, and hobbyist projects.
Whether you're building an Arduino blinking LED circuit, designing a signal panel, or experimenting with breadboard projects, this LED is a reliable and essential component. It’s designed to operate at low voltage and current, ensuring long life and safe use with controllers.

Example Circuit with Arduino:
Here’s a simple example of how to use a 5mm red LED with an Arduino to blink the LED on and off:
int ledPin = 13; // Pin where the LED is connected
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
In this example, the red LED is connected to pin 13 on the Arduino, and it will blink on and off every second.

Applications:
-
LED blink programs in Arduino and microcontroller projects
