Standard LED 5mm
A basic single-color LED. Available in red, green, yellow, blue, and white. The simplest output component for visual feedback.
Overview
A standard LED (Light Emitting Diode) emits light when current flows through it. It is the most common output component in Arduino projects, perfect for blinking indicators, status lights, and learning the basics of digital and analog output.
Specifications
| Parameter | Value |
|---|---|
| Forward Voltage | 1.8 - 3.3V (varies by color) |
| Max Current | 20mA |
Wiring Guide
| LED Pin | Arduino Pin |
|---|---|
| Anode (long leg, +) | 220-ohm resistor then digital pin |
| Cathode (short leg, -) | GND |
Use analogWrite() on PWM pins for brightness control.
Usage in ArduinoStudio
Drag the Standard LED component onto the canvas, assign a digital pin, and use the on / off / blink actions in your sequence. Connect to a PWM pin to also control brightness level.
