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

#include <Adafruit_NeoPixel.h>

#define PIN 1

Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, PIN, NEO_GRB + NEO_KHZ800);

void setup() {

   strip.begin();
// strip.setPixelColor(n, red, green, blue, white);
   strip.setPixelColor(0, 0, 0, 127);
   strip.show(); // Initialize all pixels to 'off'
   delay(2000);
}

void loop() {
  strip.setBrightness(100);
  // Some example procedures showing how to display to the pixels:
  colorWipe(strip.Color(255, 0, 0), 50); // Red
  colorWipe(strip.Color(0, 255, 0), 50); // Green
  colorWipe(strip.Color(0, 0, 255), 50); // Blue
//colorWipe(strip.Color(0, 0, 0, 255), 50); // White RGBW
  // Send a theater pixel chase in...
//  theaterChase(strip.Color(127, 127, 127), 50); // White
//  theaterChase(strip.Color(127, 0, 0), 50); // Red
//  theaterChase(strip.Color(0, 0, 127), 50); // Blue

  rainbow(20);
//  rainbowCycle(20);
//  theaterChaseRainbow(50);
}




// Fill the dots one after the other with a color
void colorWipe(uint32_t c, uint8_t wait) {
  for(uint16_t i=0; i<strip.numPixels(); i++) {

      strip.setPixelColor(i, Wheel((i+j) & 255));
    }
    strip.show();
    delay(wait);
  }
}

// Slightly different, this makes the rainbow equally distributed throughout
void rainbowCycle(uint8_t wait) {
  uint16_t i, j;

  for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel
    for(i=0; i< strip.numPixels(); i++) {

}

//Theatre-style crawling lights.

      }
    }
  }
}

//Theatre-style crawling lights with rainbow effect
void theaterChaseRainbow(uint8_t wait) {
  for (int j=0; j < 256; j++) {     // cycle all 256 colors in the wheel

      }

// Input a value 0 to 255 to get a color value.
// The colours are a transition r - g - b - back to r.
