Wired Connections

  • Pin 14 from HUZZAH to Data Input on NeoPixel
  • GND from HUZZAH to GND on NeoPixel
  • 3V from HUZZAH to PWR +5V on NeoPixel
  • EN from HUZZAH to Slide Switch
  • GND from NeoPixel to Slide Switch

Power On/Off

The slide switch opens/closes a connection to the EN (enable) pin on the Adafruit Feather HUZZAH ESP8266. 

The EN pin is connected to the 3.3V regulator. It's pulled up, so when it's connect to ground, the 3.3V regulator is disabled.
