How It Works

The Fault Finder Tool is an embedded diagnostic system built around an STM32 Blue Pill development board (F103C8T6) and programmed using the Arduino IDE. At its core, the system monitors duplicate logic contacts setup on electrical equipment to detect state transitions, such as unexpected tripping or operational changes. When the status of a connected contact changes, the STM32 microcontroller records the precise operation time and contact status. The development board interfaces with the target equipment using connecting wires routed through a prototyping breadboard to ensure secure signal connections. Once the data is captured, it can be transmitted via USB to a laptop or computer for analysis and troubleshooting. By tracking the exact sequence and timing of events, engineering students and technicians can identify root causes of equipment failure in complex systems without manual guesswork.

Frequently Asked Questions

Can I program the STM32 Blue Pill using the standard Arduino IDE?

Yes, by adding the STM32 board support package to the Arduino IDE, you can write and upload code to the Blue Pill board easily.

How does the system record the exact operation time of a fault?

The STM32 microcontroller utilizes its internal hardware timers to log the precise timestamp whenever a connected logic contact changes state.

What is the purpose of the duplicate logic contacts setup?

It allows the diagnostic tool to safely mirror and monitor the operational states of external machinery or control circuits without directly interfering with their primary functions.
