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 ...

It's estimated there are over 300 million streetlights in the world, so it's good to see they're constantly being improved, with CityTouch connectivity, glare reduction and even pole-less systems ...

The circuit uses a LED array to create a heart shape device that can be used as a gift during Valentine’s or any special occasion. The circuit uses a LED array to create a heart shape device that can ...

You’re undoubtedly familiar with the clip-on blood oxygen sensor and meter that uses a pair of LEDs and a photosensor. This non-intrusive transmissive-light device—which took decades to develop, ...

[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and ...

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 ...
