Key Features

【12-Pack Multi-Color LED Bar Graph Set 】— Includes 12 high-brightness 10-segment LED bar displays in 6 vivid colors (2× Red, 2× Yellow, 2× White, 2× Green, 2× Blue, 2× Multicolor) for clear visual indicators and color-coded project feedback.
【Time-Saving Built-in Resistor PCB Boards】 — Comes with 12 specially designed current-limiting resistor array boards (no need for 10 separate resistors per LED!); simply plug the LED bar graph directly into the PCB and insert into your breadboard — saves hours of tedious wiring and reduces errors.
【Professional 3D Printed Enclosures Included】 — 12 high-quality 3D-printed protective cases snap onto each LED bar graph, giving your projects a clean, polished, finished look while protecting the LEDs from dust and damage.
【Easy Breadboard Compatibility 】— Standard 2.54mm pin spacing; drop-in ready for breadboards, Arduino, Raspberry Pi, ESP32, or any microcontroller — ideal for beginners and advanced makers alike.
【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 】— Create stunning audio level meters (VU meters) for amplifiers, mixers, and recorders (more segments = louder volume); battery/power level indicators like old phones or power banks; WiFi/RSSI signal strength bars; sensor visualizations (light, temperature, humidity, pressure); DIY voltmeters/ammeters; retro game health/energy bars; progress indicators; and more!
