Neopixel stand

简介

Stand for Neopixel ring with 24 LEDs, a diffuser and a clock ring. My builds are a clock and a thermometer controlled by an Arduino Nano with NRF24 wireless device. Actual time and outdoor temperature is sent every minute and converted to LED-status. For the clock current hour is shown 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. Temperature is shown with a gradient color change going from green to red for 0C and above and blue to white below 0C. If temperature exceeds 20C red circle continues over the green part another lap. Below -20 it should turn purple the second lap, but that hasn't happened yet.
