5mm Green LED - Pack of 5

The 5mm Green LED - Pack of 5 is a convenient set of standard green light-emitting diodes designed for a wide range of electronics and DIY applications.

LEDs are among the most commonly used electronic components. They provide visual indication while consuming relatively low power compared with many traditional lighting technologies.

These 5mm green through-hole LEDs can be used in breadboards, prototype circuits, PCBs, robotics projects, Arduino experiments, and educational electronics applications.

Bright Green Visual Indication

Green LEDs are commonly used to provide visible status or signal indications.

They can be used as:

• Power indicators
• Status indicators
• Signal lights
• Circuit output indicators
• Decorative lighting
• Project displays

A green LED can help visually indicate the operating condition of an electronic circuit.

Standard 5mm LED Size

The 5mm package size is one of the most popular LED formats used in electronics projects.

The compact through-hole design makes it convenient for:

• Breadboards
• PCB mounting
• Prototype circuits
• Soldering projects
• Educational experiments

Pack of 5 LEDs

This product includes:

5 × 5mm Green LEDs

The pack is useful for projects requiring multiple LEDs or for keeping spare components in an electronics toolkit.

Through-Hole Design

The LEDs feature a standard through-hole configuration.

They can be used with:

• Breadboards
• Perfboards
• Prototype boards
• Printed circuit boards

The leads can be connected using jumper wires or soldered to a PCB.

LED Polarity

LEDs are polarized components, meaning they must be connected with the correct polarity.

Typically:

• Anode (+): Positive terminal
• Cathode (-): Negative terminal

In many standard LEDs, the longer lead is the anode and the shorter lead is the cathode. The flat side of the LED body is commonly used as a cathode indicator.

However, always verify the actual component orientation before installation.

Using a Current-Limiting Resistor

A suitable current-limiting resistor should normally be used when connecting an LED to a power supply or microcontroller circuit.

The resistor helps limit the electrical current flowing through the LED.

The required resistor value depends on:

• Supply voltage
• LED forward voltage
• Desired operating current

Connecting an LED directly to an unsuitable power source may damage the LED.

Arduino Projects

The 5mm Green LED is suitable for Arduino projects.

Common applications include:

• Arduino LED blinking
• Digital output indicators
• Sensor status indicators
• Traffic light projects
• Interactive electronics
• Educational programming projects

Always use an appropriate resistor and circuit configuration.

ESP32 and Microcontroller Projects

These LEDs can also be used with compatible:

• ESP32
• ESP8266
• STM32
• Raspberry Pi GPIO projects with appropriate circuitry
• Other microcontrollers

Ensure that the GPIO voltage and current limitations are considered when designing the circuit.
