The Hardware

  • A NodeMCU development board, based on the ESP8266 ESP-12E, (that you can get for under $5 from eBay). A standalone ESP8266 or a Adafruit Huzzah should work too.
  • A WS2811 or WS2812 led strip that you can get in many sizes and forms. I'm using a ring of 12 leds. When you use more than about 15-20 leds you may have to use a dedicated 5V power source.
  • Power via USB

Wiring

Assembly when using only a limited number of LEDs: Wiring schema

Alternative assembly with level shifter (something like this) for more LEDs: Wiring schema

Be careful when Assembling. The LED strips are quite sensitive concerning power supply. See https://learn.adafruit.com/adafruit-neopixel-uberguide for more information.
