Illuminate the principles of electrical circuits and semiconductor technology with this LED variety pack designed for hands-on electronics education. The 90-piece assortment features 5 mm LEDs in vibrant colors that demonstrate current flow, polarity concepts, and circuit functionality. Students can explore the fundamental properties of light-emitting diodes while creating colorful, interactive circuits that bring abstract electrical concepts to life.

This LED pack includes four solid colors-red, green, yellow, and orange-with 20 LEDs of each color for extensive experimentation. Additionally, 10 specialized bidirectional red/green LEDs provide advanced learning opportunities by demonstrating polarity reversal and dual-color functionality. This pack can help students build indicator circuits, traffic light simulators, and other educational projects that combine electronics theory with practical applications.

Perfect for physics, electronics, and STEM curricula, this LED collection supports multiple classroom demonstrations and individual student projects. The organized color variety allows teachers to assign specific colors for different circuit functions, making complex wiring diagrams easier to follow and troubleshoot during hands-on learning activities.
