- 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
