Wiring
Plug in a standard USB microphone into one of the available Raspberry Pi USB ports.
Connect a strip of NeoPixels to the Raspberry Pi using one of the following methods.
Pi Cobbler Wiring
AÂ Pi Cobbler makes the wiring easy with clearly labeled pins. A 2x20 ribbon cable connects the Pi GPIO pins to the Cobbler breakout.
To connect a NeoPixel LED strand, make the following wiring connections while the Pi is powered off and unplugged from its power adapter:
- Pi 5V to NeoPixel 5V power (red wire)
- Pi GND to NeoPixel GND (black wire)
- Pi 26 to NeoPixel DIN (green wire)
Direct Wiring
You can also wire the NeoPixels directly to the Raspberry Pi
