• Adafruit Huzzah ESP8266 breakout board but any ESP8266 board should work.
• Adafruit NeoPixel 8 ws281x LED stick but any ws281x LEDs should work.
• TI 74AHCT125 3V3 to 5V level shifter
• 5V 1A power supply sufficient is for the ESP8266 and 8 LEDs but you need a bigger power supply for more LEDs. See Adafruit tutorials for advice on powering large numbers of LEDs.
