New to using teensy and fairly new to LED WS2812B strips.
I have a pinball cabinet that I am adding LED rgb light effects to.
Issue: Connecting USB cable to computer results in power supply buzzing when orange data pair is connected to Backglass Lights. Removing the USB cable or the backglass data cable stops the power supply buzzing. Any suggestions are appreciated. I do not find any shorts. Is it possible the OctoWS2811 is bad?
Tested: Power supply connections (3) are each reading 4.94 volts at the power supply. The beginning, middle, and ends of the LED strips are reading 4.93 to 4.94 volts when USB cable is disconnected, backglass data cable connected. When USB cable is attached, the power supply begins to buzz and power supply connections are reading about 1.82 volts. Connected 46 leds from the backglass strips (last portion of light strip only, 3 strip sections) and still getting the voltage drop and buzz. Connected 163 lights from the backglass strips (1st continuous light strip only) and still getting the voltage drop and buzz. The buzzing occurs no matter what the teensy is programed to do, even the blink test.
