Clap to light switch with timer project is very useful project for power saving applications. The project switches on the LED light for 45 to 60 seconds when receives two clap sound. This project can be used in store room, toilets, dark area where switch is not visible, night lamp,...

Yann Guidon @ hackaday.io rebuild the TIL311 hexadecimal display using a pic microcontroller. He writes: The TIL311 is a nice but expensive, obsolete, power-hungry hexadecimal display. It would be cool to make a tiny module with similar functionality which solves its shortcomings. A...

A Programmable LED dimmer from Soldernerd: Around one and a half years ago I’ve designed and built various LED dimmers for both white and RGB LEDs. Then late last year someone approached me asking if I could make an RGB dimmer for him, too. But my designs were really tailored to...

T A Babu @ edn.com has a design idea of a led controller with some nice features: The key features of this Design Idea are: Soft switch on/off operation Zero current drain in sleep mode Two level dimming Low battery protection Simple controller based on CMOS 4017...

The serial controlled 50 Segment Bar-Graph Display built using CAT4016 IC. Very useful projects for development Bar-Graph based, Temperature Meter, Interactive Games, Voltage Display, Current Display., Pressure Sensor, Magnetic field meter and PH Meter. Tilt meter, LUX meter. The...

The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. You can program for the Teensy in your favorite program editor using C or you can install the...

For the exponentially growing data traffic worldwide, the data connections within and between microchips are increasingly becoming a bottleneck. Optical connections are an obvious successor, but that requires an adequate nano-sized light source – and this has now been found. Researchers...

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in...
