Barbie Arm Purse
IDEATION:
MATERIALS：
shocking pink / salmon / baby pink felt
chenille stems cure-pipes
CIRCUIT DIAGRAM:
To make the gemma show only white colors with a breathing effect.
ARDUINO:
Base on example: strandtest
Modification：
void loop() {
breathingEffect(strip.Color(255, 255, 255), 20); // White breathing effect
}
void breathingEffect(uint32_t color, int delayTime) {
// Increase brightness
for (int brightness = 0; brightness <= 255; brightness++) {
setStripBrightness(color, brightness);
delay(delayTime);
}
// Decrease brightness
for (int brightness = 255; brightness >= 0; brightness–) {
setStripBrightness(color, brightness);
delay(delayTime);
}
}
void setStripBrightness(uint32_t color, int brightness) {
// Set brightness and color to each LED
for (int i = 0; i < strip.numPixels(); i++) {
uint8_t r = (uint8_t)(Red(color) * brightness / 255);
uint8_t g = (uint8_t)(Green(color) * brightness / 255);
uint8_t b = (uint8_t)(Blue(color) * brightness / 255);
strip.setPixelColor(i, r, g, b);
}
strip.show();
}
uint8_t Red(uint32_t color) {
return (color >> 16) & 0xFF;
}
uint8_t Green(uint32_t color) {
return (color >> 8) & 0xFF;
}
uint8_t Blue(uint32_t color) {
return color & 0xFF;
}
