/*
 * Robojax Arduino Step-by-Step Course
 * Part 4: Temperature Sensors
 * Lesson 42: Introduction to LM35
 * This Arduino sketch is to use LM35 to measure temperature
 * This code has two ways to get temperature
 * 1-To print the temperature either in C, F or K on the serial monitor
 * 2-To return the value in C, F and K
 *
