Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

In this paper, the authors study human body detecting using sensor and design LED (Light Emitting Diode) control system based on star network topology of ZigBee. The human body detecting information ...

SALT LAKE CITY, UT and SANTA CLARA, CA--(Marketwired - Feb 9, 2016) - At this year's Strategies in Light show (March 1-3, 2016, Santa Clara Convention Center, Santa Clara), EnOcean will present its ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
