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 ...

Getting the 3 cent Padauk microcontroller to blink a LED. Or at least the in-circuit emulator blinking a led with C. UPDATE: ...

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 ...

The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...

Usually, an MCU is considered a digital device. By default, its output voltage level can be either high or low and nothing in between. With the requirement to create an LED brightness control, the ...

This project uses 3 lines of 5 LEDs arranged in a Y configuration to visually resemble the famous Flux Capacitor from the DeLorean time machine. The LEDs run a smooth one-direction chase effect with ...

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 ...
