241 LED Ring Clock

The clock shows the hands in diferent colors on the grid of LEDs. To make it more beautiful hands are antialiased. The brightness of the LED is calculated from the distance to the virtual pixel. I also use the milliseconds clock of the Arduino combined with the NTP clock to have a seconds hand that rotates fluently instead of ticking the seconds. https://github.com/MilovdZee/LEDCircleClock
