Hi,
Thanks for your reply.
I've got this on there at the moment:
void rgbFadeInAndOut(uint8_t red, uint8_t green, uint8_t blue, uint8_t wait) {
for(uint8_t b = 180; b <255; b++) {
for(uint8_t i=0; i < strip.numPixels(); i++) {
strip.setPixelColor(i, red * b/255, green * b/255, blue * b/255);
}
strip.show();
delay(wait);
};
for(uint8_t b=255; b > 179; b--) {
for(uint8_t i = 0; i < strip.numPixels(); i++) {
strip.setPixelColor(i, red * b/255, green * b/255, blue * b/255);
}
strip.show();
delay(wait);
};
};
I changed the colour to a pink colour. But it just fades in and out simultaneous right now and stays the same colour.
I know this is a bit of code to set up the fav colours:
#include <Adafruit_NeoPixel.h>
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream
// NEO_GRB Pixels are wired for GRB bitstream
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(6, 6, NEO_GRB + NEO_KHZ800);
Adafruit_LSM303 lsm;
// Here is where you can put in your favorite colors that will appear!
// just add new {nnn, nnn, nnn}, lines. They will be picked out randomly
// R G B
uint8_t myFavoriteColors[][3] = {{200, 0, 200}, // purple
{200, 0, 0}, // red
{200, 200, 200}, // white
};
// don't edit the line below
#define FAVCOLORS sizeof(myFavoriteColors) / 3
And this is to call a colour I think but I really don't know enough about it:
void flashRandom(int wait, uint8_t howmany) {
for(uint16_t i=0; i<howmany; i++) {
// pick a random favorite color!
int c = random(FAVCOLORS);
int red = myFavoriteColors
[0];
int green = myFavoriteColors[c][1];
int blue = myFavoriteColors[c][2];
// get a random pixel from the list
int j = random(strip.numPixels());
//Serial.print("Lighting up "); Serial.println(j);
// now we will 'fade' it in 5 steps
for (int x=0; x < 5; x++) {
int r = red * (x+1); r /= 5;
int g = green * (x+1); g /= 5;
int b = blue * (x+1); b /= 5;
strip.setPixelColor(j, strip.Color(r, g, b));
strip.show();
delay(wait);
}
// & fade out in 5 steps
for (int x=5; x >= 0; x--) {
int r = red * x; r /= 5;
int g = green * x; g /= 5;
int b = blue * x; b /= 5;
strip.setPixelColor(j, strip.Color(r, g, b));
strip.show();
delay(wait);
}
}
// LEDs will be off when done (they are faded to 0)
}
Thanks
