Using these 10-segment green LED bar graphs is a breeze. First, connect each LED's anode and cathode according to your circuit design. They're great for prototyping because of their simple hookup and compact size. Just place them on your breadboard or integrate them into your finished product. Remember, the pinout might be different from the datasheet, so if you face any issues, try rotating the device 180 degrees. For maintenance, keep them in a dry and cool place to avoid any damage. And if you're looking for different colors, we also have yellow, blue, and red ones available.
