 # led-ring-clock
-An unusual Arduino-based analog clock using an Adafruit NeoPixel ring as a display.
+An Arduino-based analog clock using an Adafruit NeoPixel ring as a display.
 
 This sketch requires the FastLED library, the Wire library (built-in), the EEPROM library (built-in), and the Adafruit RTClib.
