500 pcs 3 mm LED Light Emitting Diode Kit – Red Green Blue Yellow White (100 Each) with Storage Box | Electronic Component Set for Arduino, Raspberry Pi & Breadboard Projects | High-Brightness LEDs for STEM Education & DIY Electronics

This comprehensive 500-piece LED kit provides a full color spectrum for DIY electronics, Arduino projects, and STEM classrooms. It includes 3 mm round head light emitting diodes in five vivid colors — red, green, blue, yellow, and white — 100 pieces each organized in a durable plastic storage box.
Each LED features consistent brightness, low power consumption, and a standard lead length compatible with breadboards, PCBs, and jump wires.

The set is ideal for students learning electronics, hobbyists developing circuits, and educators designing hands-on lessons. You can use it to build indicators, light signals, robot eyes, and visual feedback systems for Arduino or Raspberry Pi projects.
Whether you are creating a line-tracking robot, testing logic circuits, or teaching basic resistor theory, this LED kit offers endless possibilities.

Each diode is manufactured with high-purity epoxy resin and nickel-plated leads for strong oxidation resistance and long service life.
Forward voltage typically ranges from 1.8 V to 3.2 V depending on color, with current ratings around 20 mA, making them safe for direct use with standard Arduino pins or through 220 Ω–330 Ω resistors.
The 3 mm diameter makes them compact enough for dense prototype boards while remaining bright and clear for indicators.

The included storage box keeps colors separated and labeled for fast access during projects. It helps learners understand electrical polarity and practice breadboarding skills.
The kit can also be used in robotic arms and IoT devices for status display, power indicators, and signal feedback. Because each LED is tested for optical consistency, you can combine multiple colors for RGB experiments and light mixing demonstrations.

From basic circuits to interactive lighting design, this LED set bridges education and innovation. It introduces students to Ohm’s law, current-limiting resistors, and series-parallel connections while encouraging creative design. Perfect for makerspaces, schools, and workshops focused on electronics and coding.
