LEDs

Appropriate light-emitting diode drivers give more flexibility in designing better energy-efficient systems.

These days, the rate of adoption for LEDs has never been higher. Shelves in the big box home improvement stores devote more space to LED bulbs than “old fashioned” incandescent bulbs, as just one example. The effect and use of LEDs is growing ...

Fluorescent and incandescent bulbs have been fixtures of the last century, but they are slowly dying out, replaced by highly efficient LED bulbs. But another form of lighting known as organic LEDs, which can be molded into panels and twisted into...

The growing number of smartphone thefts, both in the United States and abroad, has prompted manufacturers and software developers to built more resilient security measures. Fujitsu, for instance, recently released the Arrows NX F04G smartphone...

Using a simple PIC microcontroller and small program, a bicolor (red/green) LED can be controlled and directed to indicate measured voltage from 0 to 5 V using a simple pulsed code.

LEDs last longer and operate more efficiently when maintained at lower operating temperatures, as they effectively flow heat away from the active device junctions.
