Using this 10 - segment amber LED light bar graph display is a breeze. First, find a breadboard that suits your project. Since it has 20 pins with 0.1' spacing, you can easily plug it into the breadboard. You'll have plenty of room for wiring, so you don't have to worry about things getting too crowded. If you want to use it as a single - LED setup, you can treat each individual LED in the display separately. As for maintenance, keep it away from excessive moisture and dust. A dry, clean environment will help it last longer. Also, avoid applying too much power as it might damage the LEDs. When handling, be gentle to prevent any physical damage to the plastic body or the pins.
