If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT. 

In lesson 16, you were introduced to Arduino For Loops. In this lesson we show you more advanced techniques that can be used with For Loops. It is possible to do a wide array of different parameters with this command. We will demonstrate some of the interesting ways these commands can be used.
