Using this 10 - segment yellow - green LED light bar graph display is a breeze. First, find a suitable breadboard. Since it has 20 pins with 0.1' spacing, just line it up with the holes on the breadboard and gently push it in. You'll have plenty of space around it for wiring. As for driving it, if it's a multiplexed bargraph, refer to the tutorials about matrices for ideas. For non - multiplexed ones, you can check the playground article. When handling the display, be gentle as the plastic body and LEDs can be fragile. Keep it away from excessive heat and moisture to ensure its longevity. To clean it, use a soft, dry cloth. That's all you need to know to make the most of this cool display!
