Arduino Programming Language

• Int: Variables/Data Types
• begin(): function/communication/serial
• print(): function/communication/serial
• println(): function/communication/serial
• analogRead(): functions/analog I/O
• pinMode(): Functions/Digital I/O
• digitalWrite(): Functions/Digital I/O
• if: Structure/ control structure
• else: Structure/ control structure

• Comparison operators:
  • != (not equal to)
  • < (less than)
  • <= (less than or equal to)
  • == (equal to)
  • > (greater than)
  • >= (greater than or equal to)

 

• Boolean Operators:
  • ! (logical not)
  • && (logical and)
  • || (logical or)

Task 1 Develop a program and a circuit that use potentiometer to control the color of RGB LED. As the voltage reading changes, the LED color will change.

Objectives of practice:

• Practice with serial.print() and serial.println() functions that display the voltage value and color of LED in the desired format.
• Practice with analogRead() function
• Use the if and else statement to control the RGB color
• Understanding the operation of RGB LED

---

Task 2 Modify the program, change the condition of if and else statement to develop a different color pattern of RGB LED when the potentiometer is switched.

Objectives of practice:

• More practice with if and else statement
• More practice with Comparison Operator and Boolean Operators
