The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

LEDs offers a combination of flexibility and efficiency unmatched by conventional forms of lighting, and are being adopted in architectural- and stage-lighting applications because they emit highly ...

Figure 3 showed the ideal waveform for the LED current, which does not take the response time (t r) of the comparator into account. The t r of a comparator is the time it takes the output to change ...
