Control NeoPixel LED strips through an ESP8266 web server

NeoPixel LEDs are cheap and easy-to-use RGB LEDs, digitally addressable. Example code, libraries and supporting content can be found easily everywhere. In the September-October 2018 issue of Elektor Magazine one can read the extensive description of an ESP8266 web server for NeoPixel LED strips. Both the PCB and the ESP module are available from our online store.

Last week at Elektor.Labs we were honored by Coen de Bruijn stopping by to demonstrate the project he has been working on for the last year or so. Not satisfied with classic monochrome 7-segment displays we all know so well Coen set out to develop his own full-color 7-segment displays. After lots of experimenting and several rounds of prototyping finally the RGBdigit saw the light. Here is Coen's story.
