Adafruit 10 Segment Light Bar Graph LED Display - Amber - KWL-R1025UAB
Make a small linear display with a glowing amber color using this elegant LED bargraph. The color on this bargraph is similar to our yellow display but just a bit darker and with a bit more orange mixed in.
Only 1" long, it is quite visible but not so large it wont plug into a breadboard! 10 LEDs are contained in the plastic body. This display is bright, beautiful and funky with nice diffused rectangular lenses for a striking look. There are 20 pins, 10 on each side, with 0.1" spacing so you can easily plug it into a breadboard with plenty of space for wiring left over.
There is a playground article about bargraph displays. You can also just treat each individual LED as a single LED.
