Your Breadboard Works, but Can Anyone Rebuild It? From Wires to a Schematic
Series navigation: Episode 1: The Roadmap · Episode 7: Reading Arduino Pin-Current Specifications · Episode 13 The problem: The prototype works, but its meaning exists only in wire colors and memory. The goal: Convert physical connections into named, reviewable electrical intent. The result: A schematic checklist that becomes the source of truth for PCB design. AI-generated illustration of the documentation transition. It is not a circuit to copy. The prototype failed after I cleaned the desk The breadboard had worked the night before. I disconnected a few wires to organize them, rebuilt the circuit from a photo, and the sensor disappeared. The photo showed where the wires appeared to go. It did not explain which nodes were power, ground, I2C, reset, or an intentionally unused pin. It also did not reveal the breadboard's hidden internal strips. A working breadboard proves that one physical arrangement worked once. A schematic explains the intended electrical rela...
