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 ...

When it comes to ATmega8 basic I/O interfacing, we just learned how to connect a switch as an input device to control one LED connected as an output device. Now a simple tour through selected areas of ...
