16. DIGITAL OUT / DIGITAL IN
‣ Two States
‣ ON / HIGH / 1
‣ OFF / LOW / 0
‣ Port mode (in/out)
controlled by software
‣ 12 Ports available
‣ some with special functions

30. PROGRAMMING
Basic setup (bare minimum)
void setup()
{
// running one time
// do basic setup of the Arduino Board
}
void loop()
{
// running for ever
// your code
}

31. PROGRAMMING
Blink
/*void setup()
{
// Pin 13 connected
pinMode(13, OUTPUT);
}
void loop()
{
digitalWrite(13, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(13, LOW); // set the LED off
delay(1000); // wait for a second
}

32. SOME STRUCTURES
‣ Your Arduino is busy when busy
‣ One task at time
‣ The program code is executed sequentially –
step by step
‣ A command has to wait until it‘s previous has executed

33. SOME PROGRAMMING
BASICS
‣ Save and recall values
‣ int myValue = 54;
‣ Call functions
‣ digitalWrite(myValue, HIGH);
‣ myValue = analogRead(0);
‣ Conditional execution
‣ if (myValue == 54) { // } else { // }
‣ Repeat commands
‣ for(int i = 0; i<10; i++) { // }

34. SOME FUNCTIONS
‣ pinMode()
‣ digitalWrite()
‣ digitalRead()
‣ analogReference()
‣ analogRead()
‣ analogWrite() – PWM
‣ outValue = map (inValue, 0, 1023, 0, 255); //
remember range conversion
