Neopixel stand for a Neopixel ring with 24 LEDs, a diffuser and a watch ring. It displays time and temperature using an Arduino Nano with NRF24 wireless device. Time and outdoor temperature are sent every minute and converted to LED status.
For the clock, the current hour is displayed with a green, blue or red dot. Green = daytime, Blue = prepare for bed and red = night. Minutes are shown by filling white dots in the circle.
The temperature is displayed with a gradient color change that goes from green to red for 0C and above and blue to white below 0C. If the temperature exceeds 20C, the red circle above the green part continues a second round. Under -20 it was supposed to turn purple the second round, but it hasn't happened yet.
