About this product
A 10-segment linear LED bar graph in red, used to show levels such as signal strength, battery charge or sensor readings. Each segment is an individual LED that needs a current-limiting resistor or a driver circuit. Common in level meters and simple indicator projects.

Frequently asked questions
How do I drive it from an Arduino?
Each segment needs its own series resistor sized for the LED current, or you can use a bar graph driver IC such as the LM3914 for analog level indication. Keep the total current within the Arduino pin and board limits.
Can it show a sensor reading?
Yes. A bar graph displays a level in 10 steps, so map the sensor's range onto the segments in code or with a driver IC. This suits level meters and signal indicators.
