I want to build similar project like this https://youtu.be/EoGVQl3SjGY but with use of RPI 3B+
I only need to code 20LEDs (one strip) to flash randomly in various intensity and colours from (80,0,150) to (200,0,255),, no sound reactivity (only lights).
I have all hardware setup well, using adafruit library ws281x bud don't know how to code an infinite loop of flashing..
my code for now is:
from rpi_ws281x import * import random # LED strip configuration: LED_COUNT = 20 # Number of LED pixels. LED_PIN = 10 # GPIO pin connected to the pixels (18 uses PWM!). #LED_PIN = 10 # GPIO pin connected to the pixels (10 uses SPI /dev/spidev0.0). LED_FREQ_HZ = 800000 # LED signal frequency in hertz (usually 800khz) LED_DMA = 10 # DMA channel to use for generating signal (try 10) 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 # set to '1' for GPIOs 13, 19, 41, 45 or 53 strip = Adafruit_NeoPixel(LED_COUNT, LED_PIN, LED_FREQ_HZ,LED_DMA,LED_INVERT,LED_BRIGHTNESS,LED_CHANNEL) strip.begin() for x in range(0,LED_COUNT): while True: R = random.randint(80,200) B = random.randint(150,255) strip.setPixelColor(x,Color(R,0,B)) strip.show()
I know I need to somehow set the While true loop to flash/animate LEDs randomly (like with noise effect). For now all the leds are still.
Thanks in advance for help..
