In many real world applications, you want your programs to branch into different directions depending on values that you are reading from sensors. For such cases, you need to us IF statements. IF statements allow you to do different things depending on conditions. This lesson shows you how to use IF statements, and the different conditions that can be used with these commands. 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.
