4. ARDUINO
   • Microcontroller platform
   • Open source
   • You can make cool stuff with it
   • You program it with the Arduino language 

   using the Arduino software (Mac, PC, or linux)

12. WHY USE AN ARDUINO?
    • Easier to learn than alternatives.
    • Widely available for cheap!
    • Tons of code already exists.
    • Generally appropriate for real-time.
    • Not always the best choice, especially because:
    • Other options have better specs.
    • Other options use lower power.

20. EXAMPLE CODE: FLASH AN LED
    void setup () {
    pinMode(13,OUTPUT);
    }
    void loop () {
    // Turn LED on
    digitalWrite(13,HIGH);
    delay(100); // Wait 100 milliseconds
    // Turn LED off
    digitalWrite(13,LOW);
    delay(100); // Wait 100 milliseconds
    }

21. EXAMPLE CODE: BUTTON INPUT
    void setup () {
    pinMode(13,OUTPUT); // Configure Pin13 as output
    pinMode(5,INPUT); // Configure Pin5 as input
    }
    void loop () {
    // If the button is pressed...
    if (digitalRead(5)) {
    // ...then turn LED on
    digitalWrite(13,HIGH);
    } else {
    // ...if not, the turn LED off
    digitalWrite(13,LOW);
    }
    }

22. EXAMPLE CODE: SERVO MOTOR
    #include
    Servo myservo; //create servo object to control a servo motor
    void setup () {
    myservo.attach(9); //attach pin 9 to the servo object
    }
    void loop () {
    for (int i = 0; i < 255; i ++) {
    // set the servo position
    myservo.write(i); // generate PPM signal
    // wait for the servo to get there
    delay(15);
    }
    }
