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 Mini Single Bar Graph Display is a universal display containing a 10-LED bar graph to indicate the vehicle’s battery status. The Mini Single Bar Graph Display is a universal display containing a ...

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, ...

Take a gander at the Giant LED bar graph which [Chunky Hampton] recently completed (from this image we don’t think the nick name suits him). It’s simple both mechanically and electrically, but we love ...

10 LED Bar Graph battery status display Detects HIGH and LOW voltage on the vehicle battery by flashing the top or bottom LEDs, respectively Works with new generation single output Kussmaul Battery ...
