Meeting_3

1. Introduction to Arduino 3

• Developing knowledge in Arduino

2. Project to Do

• RGB LED Project
  • Build a circuit with RGB LED
  • Present the S.O.S Distress Signal by using loops
  • Present a RGB spectrum

3. Goals

• Review how to define a variable
• Learn the concept of RGB
• Learn the construction of a RGB LED
• Learn to write functions in Arduino
  • Different types of function
  • Create a function
• Learn about loops in Arduino
  • for-loop
  • while-loop
  • do-while-loop
• Try digital RGB LED combinations and use loops to present the S.O.S Distress Signal
• Learn about analog I/O (The principle is related to PWM, which we will not be covered in this meeting but it will be coverd in future meetings)
  • Try different analog RGB LED combinations
  • Create a function to optimize the code
• Learn to write codes to present a RGB spectrum
  • Hint: Use loops

4. Other Ways to Present a RGB spectrum (Advanced: Open Up Your Mind)

• Is there other way to present a RGB spectrum?
• Checkout RGBLed series 6 and 7, and see if you can understand the logic behind. Please Feel free to discuss them with your friends
  • RGBLed 6.0, 6.1, and 6.2 demonstrate another way to present a RGB spectrum by passing RGB values to a function
  • RGBLed 7.0, 7.1, 7.2, and 7.3 demonstrate another way to present a RGB spectrum by changing the output pins to a function
• Try to think about the following questions after you understand the logic behind the RGBLed series 6 and 7
  • Can you understand the differenes between these two? (Please make references to the statements above)
  • What are the differences between these two and the other one? Which one do you like the best?
• Let me know if you have any thought
