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, ...

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 ...

This application required more flexibility than the LM3914 offers, and it uses a circuit based on an Atmel AVR-family ATTiny13 microcontroller, which features 1 kbyte of program memory; a four-channel ...

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] ...

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 ...

[BikerGlen] wanted to spice up his zombie containment unit (see video below) so he designed and 3D printed some very cool looking bar graphs. Apparently, you can get curved bar graph LEDs, but only if ...
