Animates a 144 LED Adafruit DotStar strip using the pyo library to pick up and change a voice to sound kinda robotic.

Tested with a C-Media external USB sound card on a rpi4.

Plug in DotStar pins:

• Yellow: GPIO11 (SCLK) - clock
• Green: GPIO10 (MOSI) - data
• Black: GND

DotStar gets its power using 5v a micro USB.

• Micro USB pinboard
• 1000µF (6.3V or higher) capacitor close to the strip (between 5V and GND wires) to handle inrush curent.
