A 10-segment LED bar graph display in blue. At just 1" (25mm) long, it's compact enough to plug directly into a breadboard while remaining clearly visible. The diffused rectangular lenses give a clean, even glow across all 10 segments.
Each of the 10 LEDs has its own anode and cathode across 20 pins (10 per side) at 0.1" spacing, so they can be individually controlled from a microcontroller, shift register, or LED driver IC. Each segment can also be treated as a standalone LED.
Key Features
- 10 Segments – Ten individual blue LEDs in a single housing
- Diffused Rectangular Lenses – Even light output with a clean appearance
- Breadboard Friendly – 20 pins at 0.1" (2.54mm) spacing with room for wiring
- Compact 1" Package – Small enough for tight layouts, bright enough to see clearly
- Individual Control – Separate anode and cathode for each segment
Ideal For
- Audio level meters and VU displays
- Battery charge indicators
- Signal strength displays
- Arduino bar graph projects
- Status and progress indicators
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
