Week 6. Segment 1: Object Oriented Programming in Arduino Sketches

In this segment we will learn to use Object Oriented (OO) Programming. OO is a great way to generate well-structured Arduino sketches with a minimum of programming bugs. Furthermore, objects are a nice way to share code for the operation of standard hardware devices (LCD, ICs etc...) connected to the Arduino.

Goals:

• Understand the concept of Object Oriented Programming
  
• Use objects to control digital pins

In-Class Project (and probably homework):

• Translate the push button binary counter sketch into an OO sketch using a class.
  
• Call the class "BinaryCounter"
• The 'methods' of this class should be:
• void BinaryCounter::countUP(); this is supposed to increase the counter by +1.
• void BinaryCounter::countDOWN() (this is supposed to decrease the counter by -1.
• void BinaryCounter::turnDisplayOff() (this is supposed to turn all the LEDs off, that the display appears dark).
• void BinaryCounter::setValue(byte number) (this is supposed to set the counter to a specific state
• byte BinaryCounter::getValue() (this is supposed to return the current value of the counter)

Materials for this segment:

• Watch the video on the right.
  
• 'Instructable' on how to control buttons through objects.
• Commented Arduino sketch used in the video (use link below the video)
