Hello, I saw that tutorial video you posted online. I like your work very much, and I'm starting to do it now. But I had problems in the first step. Can you help me? I really want to get this lamp. I just bought a Fade Candy. He can run well on my laptop. But it doesn't work on my raspberry pie. I inserted FadeCandy into my raspberry pie, and the raspberry pie couldn't recognize it. I use this command to view the USB device I'm connected to. dmesg | tail -10 The following information appears

[ 42.691586] usb 1-1.1.2: new full-speed USB device number 7 using dwc_otg [ 42.824940] usb 1-1.1.2: New USB device found, idVendor=1d50, idProduct=607a [ 42.824955] usb 1-1.1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 42.824964] usb 1-1.1.2: Product: Fadecandy [ 42.824973] usb 1-1.1.2: Manufacturer: scanlime [ 42.824981] usb 1-1.1.2: SerialNumber: XXQKUQPZRFMGICJN [ 43.671628] Under-voltage detected!

what should I do？I use hardware in China. Voltage in China is 220 V AC

Hmmmm. Check your power supply for the Raspberry Pi? They really need to be up to spec. Even a cheap USB power cable can ruin the correct voltage supplied. Remember you are asking the Raspberry Pi to power the FadeCandy board over USB.
