Neopixel Moving Red Green and Blue

In this lab, our goal is to make a single-pixel move down the LED strip and then change color from red to green and blue.

Circuit

Code

We will use the same code that we used in the Move lab. But we will repeat the for loop three times, one loop for each color.

#include <Adafruit_NeoPixel.h>
#define PIN 2
#define NUMPIXELS 12
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  pixels.begin();
}

void loop() {
  for(int i=0;i<NUMPIXELS;i++){
    pixels.setPixelColor(i, 255, 0, 0);
    pixels.show();
    delay(100);
    pixels.setPixelColor(i, 0, 0, 0);
    pixels.show();
  }

  for(int i=0;i<NUMPIXELS;i++){
    pixels.setPixelColor(i, 0, 255, 0);
    pixels.show();
    delay(100);
    pixels.setPixelColor(i, 0, 0, 0);
    pixels.show();
  }

  for(int i=0;i<NUMPIXELS;i++){
    pixels.setPixelColor(i, 0, 0, 255);
    pixels.show();
    delay(100);
    pixels.setPixelColor(i, 0, 0, 0);
    pixels.show();
  }
}
