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.

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 ...

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 ...
