random colors and number of pixels fails #325

Hey, NOTE: my script ist completely okay.

When I start the visualization.py it will light up random leds and the number of pixels is also wrong: I changed num_pixels to 100, but all my 300 LEDS will light up randomly. My GUI is okay, but it's not transferred to the LEDS correctly.. The color and position of LEDs also update after ~1 second.

I dont know whats going on can someone help me?

Make sure your led strip and microcontroller share a common ground. You are describing behavior that typically occurs when there is no common ground. Post back here if it's already sharing a common ground, then we can go from there.

Sure, but I have a new problem.. I got "No audio input. Volume below threshold: Volume 0.0" and I changed the threshold in config.py and changed my headset. Also activated my microphone (I use "C-Media USB Headphone Set")

What is your default input device?

exiction commented 3 years ago

Im using a Headset ("C-Media USB Headphone set" and this is default)

In my config.py:

MIC_RATE = 44100 MIN_VOLUME_TRESHOLD = 1e-7
