Hi! You mentioned Arduino and Raspberry Pi as options — for voltage measurement with pass/fail logging, an ESP32 is the stronger starting point: it gives you USB serial *and* WiFi out of the box, so the same hardware supports a bench-connected CSV export today and a live dashboard later without a board swap. In a production test fixture I built for a manufacturing client, the most fragile part wasn't the voltage measurement — it was reliably associating each reading with the correct test point. We solved it with a hardware position selector rather than manual entry, and it eliminated an entire class of data corruption that was quietly invalidating test records. The voltage measurement itself, handled through a calibrated ADC with a simple resistor divider for range matching, was straightforward once the identity problem was clean. Two questions before I scope this fully: where does the captured data need to live — on-device export, PC file, or a live dashboard — and what voltage range are you testing, including whether any circuits under test carry anything above 5V? We can discuss it more in detaisl in chat. Thanks Regards

@osamaelkomy

Hi, I can seamlessly upgrade your current voltage testing device into an automated, data-logging system. Here is how I plan to approach your project: 1- Hardware Integration: Interface a suitable microcontroller (such as an Arduino Nano or Raspberry Pi Pico) with an Analog-to-Digital Converter (ADC) circuit and appropriate voltage dividers to safely read your targets. 2- Data & Logic Capture: Program firmware in C/C++ to log the precise voltage levels, evaluate pass/fail criteria based on your thresholds, and assign tracking markers for each circuit position/number. 3- Logging Output: Save the captured parameters to an onboard SD card module or stream them via UART/USB to a PC application for easy review. Also, I can replicate the system (or sample of it) at my-side to make real tests to ensure rapid turnaround and better validation. Best regards, Osama Elkomy

@Feriver

Hello, I understand you need a Microcontroller-Enhanced Testing Device solution, likely involving an embedded system that interfaces with hardware inputs/outputs to perform automated testing, signal validation, and controlled measurement of a Device Under Test (DUT). These types of systems typically combine firmware logic with hardware interfacing (GPIO, ADC, UART/SPI/I2C, relays, and signal conditioning) to enable repeatable and accurate test execution for electronic components or systems. I will design and implement a robust embedded solution built around a suitable microcontroller (e.g., STM32/AVR/ESP32 depending on requirements) that handles test sequencing, input/output control, measurement logging, and result evaluation. The deliverable will include well-structured firmware (modular C/C++), hardware interface logic (signal conditioning and I/O mapping), test automation routines, and clear documentation. If required, I can also provide a PC-side interface (Python or desktop tool) for visualization, reporting, and test control to make the system fully usable in production or lab environments. I’m ready to start immediately and can first review your exact testing requirements, DUT type, and signal/interface constraints to propose a clean architecture before implementation. Once confirmed, I will ensure the system is reliable, scalable, and optimized for real-world embedded testing workflows. Thanks, Asif
