A large heart with 20 individually controllable LEDS using 4 pins on an ATtiny 45 with Charlieplexing This is an easy to solder project, as all components are trough hole, except for the large and easy to solder battery holder Who would not like to be pledged eternal love to by their...

Vishay’s IR emitters deliver 30% higher radiant intensity in a 20% smaller footprint Vishay's optoelectronics portfolio now includes six 850 nm and 940 nm high-power infrared (IR) emitters that deliver best-in-class radiant intensity in 3.4 mm by 3.4 mm surface-mount packages. Built...

ams OSRAM’s OSLON® UV-C LEDs are suitable for a range of disinfection and purification applications. Farnell, an Avnet Company and global distributor of electronic components, products and solutions, is now stocking the full range of ams OSRAM’s OSLON® UV 3636 UV-C LEDs...

OSRAM Opto Semiconductors OSLON® Black Flat X LED Devices offers high efficiency for standard forward lighting applications. The LEDs have a high focus on system cost. The SMT device is very stable, durable and is used with standard processes. The pad geometry of the widely used OSLON...

story by Tomasz Siroń I would like to present a project developed with a passion for almost 10 years. It is a non-commercial installation of lights controlled via the Internet. The user can control the illumination in real-time using the panel on the website. I installed...

Cree LED XLamp® XHP50.3 LEDs are third-generation Extreme High Power LEDs that deliver lumen density, reliability, and optical control. The devices leverage the XHP family advantages to significantly reduce system cost by using fewer optics, PCBs, and heat sinks than with standard...

This is a 3 Digit 7-segment display project that contains 3 x Common Cathode displays, current limiting resistors or each LED segment, 3 x PNP Transistor on each common cathode for multiplexing etc. The project works with 5V TTL signals but can be optimized for 3.3V operations by...

This project will help you to easily develop an Arduino compatible project that requires 4 x -7Segment 0.5″ displays. The project consists of an Atmega328 microcontroller, 4 x BC847 NPN transistors to drive the common cathode displays. All displays are used in multiplexing...
