Week 5. Segment 2: Use of Functions

This segment focuses on the introduction of functions to organize and streamline the Arduino code and to add structure to the code.

Goals:

• Learn the use of C++ functions.
  
• Learn the use of Tabs in the Arduino IDE.
  
• Learn to use buttons as input devices on the Arduino.

In-Class Project:

• Program the 8 bit binary counter using functions. Use a pushbutton to control the counter. This is discussed in the In Class Project video.
• Added activities: Add two buttons, one to activate a 'reset' function, the other for counting backwards. Do it using functions.

Materials for this segment:

• Read the Arduino.cc document about functions and the de-bouncing of buttons.
  
• Watch the videos on the right.
  
• Use the Fritzing and iCircuit files posted below the videos.
