Instrument designs featuring a digital display may benefit from a secondary display that provides an analog version of the displayed parameter. A bar-graph display provides an easily interpreted ...

This circuit uses two National Semiconductor LM3914 dot/bar-display-driver ICs to implement a two-digit, 0 to 5V LED voltmeter that mimics a subranging flash ADC. An LED bar graph comprising five LEDs ...

The driver board with display attached; the row of lamps is visible on the right hand side. LEDs weren’t always an easy solution to displays and indicators. The fine folks at [Industrial Alchemy] ...

Targeting indoor applications such as audio and video products, consumer electronics, and panel instrumentation, this 20-segment bar graph is available in either lunar white light (see photo) or blue ...
