interstellar-time-dilation

A time dilation calculator of Miller's planet from Interstellar.

Arduino

Nokia 5110 LCD

From left to right:

• RST: pin 8
• CE: pin 9
• DC: pin 10
• Din: pin 11
• CLK: pin 12
• Vcc: pin 5V
• BL: pin 5V with 330ohm resistor
• Gnd: pin GND

Library

Uses Rinky-Dink Electronics' LCD5110 Graph library to print time on Nokia 5110 display (available on LCD5110_Graph).

#include <LCD5110_Graph.h>

Code

Using a Nokia 5110 display (84x48 pixels), LCD5110.print parameters are:

LCD5110.print(string text, int x, int y); 

So, for a 84x48 display the code'll be like:

screen.print("INTERSTELLAR", CENTER, 0);                          // First line (0) print
screen.print("Time dilation", CENTER, 8);                         // Second line (8) print
screen.print("Miller's Time:", CENTER, 16);                       // Third line (16) print
screen.print(String(seconds)+"s", CENTER, 24);                    // Fourth line (24) print
screen.print("Earth Time:", CENTER, 32);                          // Fifth line (32) print

screen.print(String(nYears)+" years", CENTER, 40);                // Sixth line (40) print, if nYears > 2

I want to use it without Nokia 5110, how?

You may want to use these variables:

  timeDilation = seconds * timeFactor; // Seconds on Miller's -> Second's on Earth conversion
  nYears = timeDilation/yearSec; // Where nYears = number of years passed on earth based on Miller's time dilation 

There is a serialtimedilation.ino example that uses Serial to print values.
