Dark activated LED light is a simple project which operates a LED when the light falling on the LDR goes below a set point. The circuit is built using LM393 comparator, LDR as light sensor, preset (potentiometer) for sensitivity adjustment, transistor to drive the LED. The project can also be considered for use in energy

There has not been a simple addressable LED library for PIC32 microcontrollers until now! The PICxel library is an MPIDE library that handles the timing required to use addressable LEDs (WS2812, WS2811) or more commonly known as Adafruit Neopixels. Going through through a couple steps will allow your to get started with the PICxel library.

With all LEDs you will need a power supply, some sort of way to send a signal (usually a microcontroller) and method of connecting the LED to your system… Admittedly, that sort of explanation is all things pretty vague (as a description), so instead it’s my opinion that the easiest way to explain the LEDs

1. Quite a few POV clocks out there, why is this special? Well, mainly because it’s mine. There are quite a few POV clocks out there on the web using all sorts of display mechanisms, chassis, controllers. The one I decided to build isn’t exactly one of them, the main difference being in the way

Description The LT3799 is an isolated flyback controller with power factor correction specifically designed for driving LEDs. The controller operates using critical conduction mode allowing the use of a small transformer. Using a novel current sensing scheme, the controller is able to deliver a well regulated current to the secondary side without using an opto-coupler.

Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer. The proof-of-concept device produced a beam with 50% of light in 36 degrees, and over 90% efficiency. “Most package manufacturers design their LED packages for maximum light extraction. This means as little manipulation of
