title: meaning of setCursor(X,Y) coordinates
body: <p>This example sketch shows how to use the setCursor() method to reposition the cursor. To move the cursor, just call setCursor() with a row and column position. For example, for a 2x16 display:</p>
  
  <pre class="lang-cpp prettyprint-override"><code>lcd.setCursor(0, 0); // top left
  lcd.setCursor(15, 0); // top right
  lcd.setCursor(0, 1); // bottom left
  lcd.setCursor(15, 1); // bottom right
  </code></pre>
  
  <p>I am not able to understand the above code.Can anyone please give the clarification for the same?</p>
