In this article learn about the LM3914 Dot/Bar Display Driver IC. This IC reads an analog voltage and converts this value to a display of 10 LEDs in bar or dot format. This is a nice component to experiment with. On the video above see a demonstration of LM3914 as a voltmeter with a range of 0~5VDC.
