Using this 10-segment LED bar graph is a breeze. First, you'll want to connect it according to the pinout. Just keep in mind that the actual pinout might be different from what's on the datasheet. If that's the case, simply rotate the device 180 degrees so that pin 11 becomes the first pin. It's great for prototyping projects. You can quickly set it up because of its compact size and easy hookup. And it's also suitable for finished products. We offer it in different colors like red, yellow, blue, and green, so you can choose the one that fits your needs. As for maintenance, keep it in a clean and dry place. Avoid exposing it to extreme temperatures or humidity. That should keep it working well for a long time.
