//This is a simulation of an solar tracker using an Arduino UNO R3.
/* 
  We have 2 LDR sensors and 1 servo motor. In real life when more light is going down
  on either one of the sensors, the solar panel will rotate in that direction.
  In this example, the hypothetical solar panel rotates only on one axis!

const int sensorMax2 = 100000; //Sensor maximum...
