====== Programming concepts ======

This crash course hasn't covered advanced but crucial programming concepts. You are strongly advised to read about control structures on the [[http://arduino.cc/en/Tutorial/HomePage|Arduino Tutorials]] pages. The [[http://arduino.cc/en/Tutorial/IfStatement|if statement]] selection structure and [[http://arduino.cc/en/Tutorial/WhileLoop|while loop]] and [[http://arduino.cc/en/Tutorial/ForLoop|for loop]] repetition structures are particularly important.
