- 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
- 17. DIGITAL OUT /DIGITAL IN voltage HIGH 5V+ 4 3 2 1 LOW GND 0 1 2 3 4 5 6 7 8 9 10 time
- 18. DIGITAL PORTS “input” “output” On/Off On/Off
- 19. ANALOG PORTS ‣ Value range instead of state ‣ Input 0 -1023 ‣ Output 0 -255 (analog output shared with digital out)
- 20. ANALOG PORTS 0 1023 255 0
- 21. ANALOG IN voltage 5V+ 4 3 2 1 GND 0 1 2 3 4 5 6 7 8 9 10 time
- 22. ANALOG OUT ‣ Thereis no real variable voltage output ‣ Analog signal is generated by waveform with constant voltage and constant frequency
- 23. ANALOG OUT voltage 5V+ 4 3 2 1 GND 0 1 2 3 4 5 6 7 8 9 10 time
- 24. ANALOG OUT Always same period voltage Always 5V 5V+ 4 3 2 1 GND 0 1 2 3 4 5 6 7 8 9 10 time
- 25. ANALOG OUT Always same period voltage Always 5V 5V+ 4 Getting different values by moving the middle 3 line within the period 2 1 GND 0 1 2 3 4 5 6 7 8 9 10 time

- 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 ‣ YourArduino 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 See http://arduino.cc/en/Reference/HomePage
