This circuit uses 10 LEDs to produce the effect of a single LED continuously moving back and forth in a line. The circuit comprises of two main parts, a triangle wave oscillator and an LED bargraph.

In addition to coming in white and blue colors, this seven-segment LED display and bargraph employs a contrasting black face color that enhances the white and blue light output. This makes the white ...

LEDtronics introduced linear bargraph LEDs that are designed to be readable in sunlight and to improve the visual information presentation on aviation industry panels. The bargraph LEDs come in two ...

The LM3914 is a truly versatile component. Besides LEDs, only a few other components are needed to make the ‘bidirectional’ bargraph voltmeter shown here. The circuit is similar to a conventional bar ...

Relying on 51 LEDs to provide a uni- or multi-color bargraph, the model LPB loop-powered bargraph is configurable for one, three, or five pointers or full bars. The unit is 4 mA-to-20mA powered and ...
