NeoPixels are “intelligent” full-color RGB LEDs that can be controlled and chained from a single microcontroller pin. This guide presents an overview of NeoPixel products, along with tips for building and powering projects of all shapes and sizes.
Adafruit Industries, Unique & fun DIY electronics and kits NeoPixel RGBW Mini Button PCB - Pack of 10 : ID 4776 - These are the smallest NeoPixel breakouts around! Tiny, bright RGB+White pixels to your project. These little PCBs are only 9.1mm x 9.1m
In this tutorial I show how you can make a minimalist clock synchronized with the internet. I tested it with two different ESP8266 based boards: Firebeetle and NodeMCU. The microcontroller gets current time from a Google server, and displays it on a NeoPixel LED ring. It also receives current...
