The project can be used effectively to detect fast moving objects using sensors made from LED array. One of the slave microcontrollers (Slave A) is the PIC16F876A which autonomously scans the bottom ...

All too often component manufacturers are the unsung heroes behind a great product. It's easy to recognize the brand whose name is on the box, but a large part of the work that goes into making a ...

Schematic and operation of a capacitorless active-matrix micro-LED pixel, where a single memristor (1M) substitutes both the storage capacitor and the driving TFT. The compact 1M cell can be ...

Researchers from the University of Illinois at Urbana-Champaign have created bio-compatible LED arrays that can bend, stretch, and even be implanted under the skin. While this might cause some people ...

A solar day lamp is a simple, inexpensive device for bringing “daylight” to dark interior spaces whenever the sun is shining. This article provides complete instructions for designing lamps using both ...

LumiBright UV boards, leveraging chip-on-board LED technology with metallic-core printed-circuit-board (PCB) substrates, feature a large emitting area using a closely packed array of UV LED chips to ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition ...

This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...
