Hardware
- A NodeMCU development board, based on the ESP8266 (you can get this for under $5 from eBay). A standalone ESP8266 or an 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
Assembly when using only a limited number of LEDs:
Alternative assembly with level shifter (something like this) for more LEDs:
Be careful when Assembling. The LED strips are quite sensitive concerning power supply. See the Neopixel Uberguide for more information.
Note: For circuit layout shown above, LED_PIN in definitions.h must be changed from 14 to 5.
