The circuit shown above is designed to receive temperature and humidity data and display it on the Neopixel ring. I used a DHT11 from Adafruit for temperature and humidity data, as well as a 16 Neopixel ring, The capacitor is used to prevent a burst of energy from jolting the Neopixels. The button is used to turn on the entire project for 20 seconds, but was not included in the code due to this project being done on an Arduino Uno while plugged into a computer or wall.
