According to FlatpanelsHD and TheWalkmanblog, Sony has trademarked “True RGB” in Japan and Canada. It’s almost certainly for the RGB TV technology announced earlier this year to compete with similar ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

On paper, LED bulbs are made to last for at least several years thanks to their low energy needs. I wanted to know why that doesn't always work out, so I talked to installers and LED manufacturers to ...

Chris Wedel is a fan of all things tech and gadgets. Living in rural Kansas with his wife and two young boys makes finding ways to stay online tricky — not to mention making my homestead smarter.

Abstract: A real-time high-speed visible light communication (VLC) system based on RGB-LEDs is proposed in this paper. With the use of the wavelength-division multiplexing (WDM), the system enables ...

Abstract: Aiming at the problem of whether the color difference exceeds the threshold when the RGB-LED is lit and how to calibrate the deviation, this article proposes an RGB LED chromaticity ...

My initial goal was to have a remote display that would show multiple kind of information and run reliably 24/7. Can be connected to the local network via WiFi and controlled via REST API or Websocket ...

The map2colour library is used to map a float value to a colour in the RGB spectrum. The float value can be the result of a calculation or read from a sensor, e.g. temperature, humidity, light, ...
