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, ...

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 ...

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 ...

[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 ...
