Using this 10 - segment blue LED light bar graph display is easy. First, find a suitable breadboard and carefully plug the display into it. The 0.1' spacing between the pins makes it straightforward to connect. When it comes to powering it, refer to the tutorials about matrices for driving a multiplexed bargraph. For the best results, keep the display away from direct sunlight and extreme temperatures. If it gets dirty, use a soft, dry cloth to gently wipe it. Don't use any harsh chemicals as they may damage the plastic body or the LEDs.
