VoiceTurn - Wiring Diagram

Wiring:
- RED (supply voltage): from Arduino's 3V3 pin to both LED strips' 5V pin.
- GREEN (data, left): from Arduino's D4 pin to left LED strip's data input pin (DI).
- YELLOW (data, right): from Arduino's D7 pin to right LED strip's data input pin (DI).
- BLACK (ground): from Arduino's GND pin to both LED strips' GND pin.

The 3.5 mm jack - plug 4 pin connectors and cable separate the setup into two modules for easier handling and mounting.
