In Python, how about:
import time
from neopixel import *
# LED strip configuration:
LED_COUNT = 60 # Number of LED pixels.
LED_PIN = 18 # GPIO pin connected to the pixels (must support PWM!).
LED_FREQ_HZ = 800000 # LED signal frequency in hertz (usually 800khz)
LED_DMA = 5 # DMA channel to use for generating signal (try 5)
LED_BRIGHTNESS = 255 # Set to 0 for darkest and 255 for brightest
LED_INVERT = False # True to invert the signal (when using NPN transistor level shift)
LED_CHANNEL = 0
LED_STRIP = ws.SK6812_STRIP_GRBW
def fade(r1,g1,b1,w1, r2,g2,b2,w2, steps,interval):
lastUpdate = time.time() - interval
for i in range(1, steps + 1):
r = ((r1 * (steps - i)) + (r2 * i)) / steps
g = ((g1 * (steps - i)) + (g2 * i)) / steps
b = ((b1 * (steps - i)) + (b2 * i)) / steps
w = ((w1 * (steps - i)) + (w2 * i)) / steps
while ((time.time() - lastUpdate) < interval):
pass
# print("{: 3d} ({:0.3f}s): {:03d}, {:03d}, {:03d}, {:03d}".format(i, time.time() - lastUpdate, r, g, b, w))
color = Color(r, g, b, w)
for j in range(strip.numPixels()):
strip.setPixelColor(j, color)
strip.show()
lastUpdate = time.time()
strip = Adafruit_NeoPixel(LED_COUNT, LED_PIN, LED_FREQ_HZ, LED_DMA, LED_INVERT, LED_BRIGHTNESS, LED_CHANNEL, LED_STRIP)
strip.begin()
fade(255,0,0,0, 10,255,0,0, 40,0.025)
Wow this looks great! Im going to try tonight, ill let you know the outcome.
Closing issue due to inactivity.
Hi, I would really love to use an effect to fade from color1 to color2, and even better would be to face from color1 with brightness1, to color2 with brightness2 in X number of steps.
How could i best achieve this effect? It could look very much like this
