The LM3914 and LM3916 are a two ICs in a series of monolithic, analog-controlled LED drivers. With these chips, all it takes is a single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain point turn on) or dot mode (with only a single LED on at a time).

How to Build an LM3914 Dot/Bar Display Driver Circuit. In this project, we are going to show how to connect a LM3914 dot/bar display driver so that it can control 10 LED outputs. With this LM3914 chip, we can control an LED bar graph in either bar mode or dot mode.
