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 ...

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 project was based on AVR AT90S8515 and HDSP8820 to create a bar graph which can be modified to move the light from side to side that is similar to knight rider bar. The design of the device ...

Last year at the 2014 NC Maker Faire, Manical Labs brought a large LED display. Blinking LEDs and pixel animations are always welcome, but at 24 inches square this build was impressive, but it wasn’t ...

Micro LED technology is limited to applications in high-end large-size commercial displays and deluxe home theater systems currently due to high production cost, but technological improvements are ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...
