Since there isn't one single famous academic paper dedicated specifically to the Fritzing diagram of a solenoid lock (as Fritzing is a design tool rather than a research topic), I have compiled a below.
This "paper" provides the solid engineering analysis you are looking for. It covers the theory, the critical hardware interface (the transistor driver), and an analysis of the Fritzing wiring diagram itself. Abstract This paper details the electronic design and implementation of an electric solenoid door lock system using the Fritzing design environment. It addresses the core engineering challenge of interfacing a low-voltage microcontroller (Arduino) with a high-power inductive load (Solenoid). The primary focus is on the design of the driver circuit (using a MOSFET/Transistor), the necessity of protective flyback diodes, and the interpretation of the schematic and breadboard views within Fritzing. 1. Introduction Electric solenoid locks are standard components in modern access control systems. Unlike magnetic locks (maglocks) which require constant power to secure, solenoid locks typically utilize a "fail-secure" mechanism, requiring an electrical pulse only to unlock.
