http://www.microchip.comLEDs have been a mainstay in modern electronics for over 30 years. Their design requirements are common knowledge, and most designers don't ...

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 ...

Whether you’re into chiptune or just playing Tetris on original hardware, you might like rocking a heavily-customized Game Boy. Lovely flashing LEDs can only improve the aesthetic, so if that’s what ...

Driving more than a handful of LEDs from a microcontroller is often a feat that takes tedious wiring, tricking the processor, or a lot of extra external hardware. Charlieplexing is perhaps the most ...

Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...
