A 10-segment LED bar graph display in yellow-green. 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 yellow-green 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

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- 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 single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
