Red 5mm LED

Red 5 mm LED – Displays Category
The Red 5 mm LED is a compact, through‑hole light‑emitting diode that delivers a vivid, eye‑catching red glow in a standard 5 mm package. Designed for easy insertion into breadboards and perf‑boards, it operates at a typical forward voltage of 2.0 V and a safe continuous current of 20 mA, making it ideal for beginner‑level circuits as well as more advanced prototyping projects.

When students work with this LED they’ll explore fundamental concepts such as voltage, current, resistance, and the physics of light. They’ll practice calculating resistor values with Ohm’s law, build simple series and parallel circuits, and integrate the LED into microcontroller‑driven projects (Arduino, Raspberry Pi, micro:bit) to learn basic programming and sensor feedback loops. The hands‑on experience reinforces problem‑solving, troubleshooting, and documentation skills that are core to STEAM learning.

Key Features

• Bright, consistent red output (≈150 mcd) for clear visual feedback
• Low forward voltage (≈2.0 V) and 20 mA max current – safe for classroom power supplies
• Durable, lead‑free, 5 mm through‑hole package – fits standard breadboards and kits
• Long‑life (≥50 000 hours) for repeated use across projects

Because the Red 5 mm LED bridges Science (light wavelength, energy conversion), Technology (circuit design, microcontroller control), Engineering (prototype building, iterative testing), Art (color, visual storytelling), and Math (calculations, data analysis), it serves as a versatile entry point for interdisciplinary STEAM curricula. Its simplicity encourages experimentation, while its reliability supports deeper, project‑based learning that connects theory to real‑world applications.
