Using this 10-segment yellow LED bar graph is easy. First, connect it according to the pinout, though remember it might be different from the datasheet. If you face issues, just rotate the device 180 degrees. You can use it in your prototypes to quickly test your ideas or integrate it into finished products. We also have the same bar graph in red, blue, and green if you need different colors. When it comes to maintenance, keep it in a dry and clean place. If you have any questions, refer to the datasheet or watch the YouTube video demo.
