The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display.
One pin changes the display from a bar graph to a moving dot display.
LED current drive is regulated and program
