You need following parts for this beautiful clock:
- Arudino Mini Pro
- digital RGB LED-Stripe (1m, 60 LEDs)
- Bamboo pizza plate (32cm circumference)
- RealTimeClock Module for Arduino
- 3,3v Voltage regulator (for the RTC module)
Just stick the LED-Stripe around the pizza plate and connect the RTC and the LED-Stripe to the Arduino Mini Pro.
The hour indicator is red, the minute indicator is cyan.
You can find Information about the LED-Stripe Arduino connection at Adafruit (https://learn.adafruit.com/digital-led-strip/overview).
