Color-Coded Wiring Guide for Easier Prototyping

Wire Color	Recommended Use	Description
Red	Power (+V / VCC)	Use for supplying positive voltage from a power source or microcontroller.
Black	Ground (GND)	Standard color for ground rails; ensures consistent 0V reference.
Yellow	Signal Line	Commonly used for GPIO signals, data lines, and sensor outputs.
White	Alternate Signal Line	Useful for organizing multiple signal connections.
Blue	Communication / Secondary Signal	Often used for I2C SDA, UART RX, or distinguishing special signals.
Green	Control / Trigger	Ideal for control inputs such as enable pins or triggers.
Orange	Secondary Power Rail	Good for separating 3.3V and 5V power lines when red is already used.
Purple	Clock / Special Communication	Great for SPI clock, I2C SCL, or interrupt pins.
Gray	General Purpose	Used for extra signals, debugging, or miscellaneous wiring.
Brown	Analog / Reference Line	Suitable for analog grounds, reference lines, or sensor-specific needs.
