Using this 10-segment blue LED bar graph is easy. First, connect each of the individual LEDs through their anode and cathode connections. Since it has a compact size and simple hookup, it's great for quick prototyping. You can use it in a variety of projects. We also have these LEDs in other colors like yellow, red, and green, so you can choose based on your needs. Just be aware that the pinout might not match the datasheet. If you find a difference, rotate the device 180 degrees and pin 11 will be the first in line. As for maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If you need more details, check out the datasheet and the YouTube video demo.
