Analog clock using math, Arduino pro mini, DS3231 and Nokia 5110

This project shows you how to build an analog clock with an Arduino pro mini, a DS3231 real time clock module and a Nokia 5110 LCD display. It is explained how to convert the digital signal from the real time clock module into an analog format using mathematics, especially trigonometric functions like sine and cosine and provides you the code. The text, pictures, Arduino code and Excel sheet for calculation can be found unter: https://www.instructables.com/id/Analog-Clock-Using-Math-Arduino-Pro-Mini-DS3231-an/
