【12-PACK MULTI-COLOR LED BAR GRAPH SET】Includes 12 ten-segment LED bar displays in 6 colors (2× Red, 2× Yellow, 2× White, 2× Green, 2× Blue, 2× Multicolor) for visual indicators and color-coded project feedback.
【BUILT-IN RESISTOR PCB BOARDS】Includes 12 current-limiting resistor array boards — no need for 10 separate resistors per LED bar. Plug the LED bar graph into the PCB and insert into your breadboard, reducing wiring and errors.
【3D-PRINTED ENCLOSURES INCLUDED】12 3D-printed protective cases snap onto each LED bar graph for a finished look while protecting the LEDs from dust and damage.
【BREADBOARD COMPATIBLE】Standard 2.54mm pin spacing — drop-in ready for breadboards, Arduino, Raspberry Pi, ESP32, and other microcontrollers. Suitable for beginners and advanced makers.
【Ultra-Bright & Reliable Performance】 — High-visibility segments light up clearly even in ambient light; low power consumption, long lifespan, and perfect for analog-style displays.
【VERSATILE APPLICATIONS】Build audio level meters (VU meters), battery/power level indicators, WiFi/RSSI signal bars, sensor visualizations (light, temperature, humidity, pressure), DIY voltmeters/ammeters, retro game health bars, and progress indicators.
【Complete Ready-to-Use Kit 】— Everything you need in one package for multiple projects — great value for hobbyists, educators, STEM teachers, and electronics enthusiasts.
