What a wiring diagram is.
A wiring diagram shows the physical connections between components: where each wire starts, where it ends, and how power and ground are shared. Unlike a schematic, it is arranged around the actual parts and connection points.
For a small electronics build, a breadboard wiring diagram helps you assemble and inspect the circuit before you power it. Check component ratings and the manufacturer's pinout before connecting hardware.

Common questions
What is a wiring diagram?
A wiring diagram shows how components are physically connected. It focuses on wire routes, terminals and pin connections rather than abstract circuit logic.
How is a wiring diagram different from a schematic?
A schematic uses standard symbols to show electrical function. A wiring diagram shows the practical layout and connections used to assemble or repair a circuit.
What should I include in a wiring diagram prompt?
Name the board and components, state the power supply, and list the pins or terminals that connect. Include values such as a resistor value where they matter.
Can I use it for mains wiring?
Use it for planning and documentation, but have mains work designed and checked by a qualified electrician under the applicable local rules.
