Svetielkujúci Workshop 7. a 14. 6. 2017


Úvod

Krok za krokom

1. Blink

2. Železničné priecestie

3. K.I.T.T. 2000

4. Ak to nefunguje...

...tak skontrolujte nastavenia.

Druhá časť

Adafruit Gemma

V programovacom prostredí Arduino treba najprv nastaviť typ elektronickej dosky na Adafruit Gemma 8MHz v menu Tools->Board.


Potom ešte treba vybrať vhodný programovací protokol - vyeberiete ho z menu Tools->Programmer->USBtinyISP


Vyskúšame postupne jednoduché programy 

/*   Blink 1  */
 
#define RED_LED 1

void setup() {
  
  pinMode(RED_LED, OUTPUT);

}

void loop() {
    digitalWrite(RED_LED, HIGH); 
    delay(200);
    digitalWrite(RED_LED, LOW);
    delay(200);
}



/*   Blink 3  */
 
#define RED_LED 0
#define GREEN_LED 1
#define BLUE_LED 2

void setup() {
  
  pinMode(RED_LED, OUTPUT);
  pinMode(GREEN_LED, OUTPUT);
  pinMode(BLUE_LED, OUTPUT);

}

void loop() {
    digitalWrite(RED_LED, HIGH); 
    delay(200);
    digitalWrite(RED_LED, LOW);
    delay(200);

    digitalWrite(GREEN_LED, HIGH); 
    delay(200);
    digitalWrite(GREEN_LED, LOW);
    delay(200);

    digitalWrite(BLUE_LED, HIGH); 
    delay(200);
    digitalWrite(BLUE_LED, LOW);
    delay(200);

}

NeoPixel RGB

Priklady práce s inteligentnou RGB LED diódou Neopixel.

   LED.setPixelColor(0, 0, 0, 127);

   delay(2000);
   LED.setBrightness(100);
   }
 
void loop() {  
 //                 n   R   G   B  
  LED.setPixelColor(0, 255, 0, 127);
  delay(2000);
  LED.setPixelColor(0,  0 , 0, 0);
  delay(2000);

     LED.setPixelColor(0, 255, 0, 0);  // First LED Red
     LED.setPixelColor(1, 0, 0, 127);  // Second LED Blue
     delay(300);
     LED.setPixelColor(0, 0, 0, 127);  // First LED Blue
     LED.setPixelColor(1, 255, 0, 0);  // Second LED Red
     delay(300);
