White 5 mm LED – Displays
A compact, high‑intensity white light source, the 5 mm LED is a staple component for any electronic or optical project. Housed in a durable through‑hole package, it snaps easily onto a breadboard or perfboard, delivering bright, uniform illumination with a low forward voltage (≈2.0 V) and minimal power draw. Perfect for signaling, indicator lights, light‑up models, and low‑cost displays, this LED works seamlessly with Arduino, Raspberry Pi, and classic circuit kits.
What students will learn – By wiring the LED into circuits, learners explore fundamental concepts such as voltage, current limiting, series‑parallel networks, and pulse‑width modulation (PWM) for brightness control. They also experiment with color mixing, light diffusion, and sensor feedback, building a foundation in electronics, programming, and optics.
Key features
- Standard 5 mm through‑hole package, easy to insert on breadboards
- Bright white output (≈150 mcd) with a wide viewing angle (≈120°)
- Low forward voltage (≈2.0 V) and current‑limiting recommended at 20 mA
- Long‑life semiconductor (≥50 000 h) and robust epoxy coating
- Compatible with most microcontroller shields and prototyping kits
Why it’s great for STEAM education – The white LED bridges science (light physics, energy conversion), technology (circuit design, microcontroller integration), engineering (prototype building, troubleshooting), art (light‑based installations, color theory), and mathematics (calculating resistor values, timing equations). Its instant visual feedback makes abstract concepts tangible, encouraging curiosity, iterative design, and interdisciplinary creativity in the classroom.
