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 circuit in Figure 1 uses only five I/O lines to drive a dot- or bar-graph display of 20 LEDs. Although this version of the design uses a small and inexpensive one-time-programmable microprocessor, ...

Model SEB (switchboard LED bar graph) can be used as an indicator only with no output; with V/mA or serial input as a remote display); or as an indicator/controller with outputs such as relays, analog ...

This file type includes high resolution graphics and schematics. LEDs often are used to form a dot/bar graph display. 1-4 You also can use an LED dot-graph display as a complement to a digital ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

The Mini Single Bar Graph Display is a universal display containing a 10-LED bar graph to indicate the vehicle’s battery status. The Mini Single Bar Graph Display is a universal display containing a ...

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 ...

Isn’t it always the way? There’s a circuit right out of the textbooks, or even a chip designed to do exactly what you want — almost exactly. It’s 80% perfect for your application, and rather than ...
