Arduino Industrial Counter & Timer

@deeproadrash

Hello, I have worked with Timers & Counters, WiFi, REST API, Arduino. I can fix the issues & provide you production ready system. I can also do long run test.

@elect2eng

I have good experience in programming Arduino based hardware. Can you please send me the schematic and the arduino board, sensor etc. I can start the job immediately after getting the board. Please Let me know if you have any questions. What is the count speed? is it debounced? what timing intervals are used?

Hello, I will develop the optimized Arduino firmware and update your hardware schematics for the industrial counter and timer system. To eliminate logical drift, I will implement a non-blocking, interrupt-driven counting routine in your C++ code. I will configure the LCD interface to display clear formatting of counts, elapsed time, and Wi-Fi link status icons. For the ESP-01 Wi-Fi module over UART, I will write a robust communication driver using AT commands or a stable wrapper, incorporating auto-reconnect parameters and error handling to publish data packets reliably to your REST endpoint. Finally, I will deliver the updated schematic and BOM inside a standard CAD tool. Because I operate remotely and cannot physically receive your shipped prototype, I will deliver the files and guide you step-by-step through remote serial validation to verify the target timing and counting accuracies. I have extensive experience writing high-reliability Arduino firmware, configuring low-level UART-to-WiFi bridges, and designing manufacturing-ready schematics and bill of materials. 1) Which specific Arduino board, such as the Uno, Nano, or Mega, is the core of your prototype? 2) Is the physical count input triggered by a simple mechanical switch or a digital sensor like an optical or proximity sensor? 3) Which specific CAD software, such as KiCad or EasyEDA, do you prefer for the schematic and BOM deliverables? Thanks, Bharat

Hi, I have experience with non-blocking embedded logic, LCD interfaces, ESP-01 UART communication, automatic Wi-Fi reconnection, and REST data publishing, and I will deliver clean, well-commented code, an improved LCD layout, updated schematic and BOM, plus a clear test report covering count accuracy, timing tolerance, and 48-hour uptime. I can work directly from your labelled prototype and wiring diagram, structure the project around agreed milestones, and provide revisions quickly as you test each build.

Hi, I can make your Arduino-based industrial counter and timer prototype production-ready by fixing the counting/timing logic, stabilizing Wi-Fi communication, improving the LCD display, and updating the schematic/BOM. The best solution is to first review your labelled hardware, current sketch, wiring diagram, sensor input method, LCD interface, ESP-01 UART setup, and REST API payload format. I’ll then rewrite the firmware with non-blocking timing, interrupt-safe counting, reconnection handling, payload retry logic, and clear LCD status feedback. I’m comfortable with Arduino firmware, ESP-01 Wi-Fi communication, UART debugging, LCD interfaces, REST API publishing, industrial counters, timer accuracy, embedded testing, schematic cleanup, BOM preparation, and long-run validation. Deliverables will include: * Clean Arduino source code * Reliable counter and timer logic * LCD count/time/status display * ESP-01 reconnect and publish routine * REST API payload handling * Updated schematic * Updated BOM * Accuracy and uptime test report * 48-hour run-test notes * Production handover documentation I’ll focus on stable operation, accurate counting, reliable timing, and clear documentation so the unit can be reproduced by a contract manufacturer without confusion. Best regards Ankit

Hello You do not have to ship the hardware to me , most enhancements and fixes could be done remotely while being in your real environment. I have long experience with similar projects. Let me know if you would like to have a quick chat. Looking forward to working with you.

@ASSAMWEB

Greetings, I have reviewed your project posting. However, the description doesn’t include enough details to accurately assess the scope. Please open a chat so we can discuss your requirements in detail and identify the best solution for your needs. Regards

Built and shipped exactly this stack before; Arduino dual-loop counting/timing, LCD status displays, ESP-01 UART WiFi with REST push. Know where prototypes like yours usually drift: non-blocking timers instead of delay(), debounced counter ISR, and a watchdog + auto-reconnect on the ESP-01 so WiFi doesn't silently die under load. Plan: Pull your sketch + wiring diagram, diagnose the drift and WiFi instability first (usually blocking code or brownout on the ESP-01). Rewrite core logic; clean, commented, millis()-based state machine for count + timer in parallel. LCD layout: count, elapsed time, connection/status icon. Robust WiFi publish routine ;retry/backoff, reconnect logic, REST POST to your endpoint. Updated schematic + BOM, CM-ready. 48-hr burn-in test, deliver accuracy/uptime report. Can start as soon as the unit ships to me. Fast iteration, same-day flashes on revisions.

@namanpathak73

Hello, I’m very interested in your project because it closely matches a production monitoring system I have already developed and deployed in a manufacturing environment. I work as a Manufacturing Excellence Executive and have hands-on experience designing industrial IoT solutions using Arduino, Raspberry Pi, laser sensors, LCD displays, Wi-Fi communication, and real-time production dashboards. I have successfully built a real-time production counting system that monitors multiple conveyor lines with 99.5% counting accuracy, displays live production data, and sends information to cloud dashboards. This experience gives me a strong understanding of building reliable industrial devices rather than simple hobby projects. I can Show you the images and the live dashboards deployed to show to actual data on TV automatically. Perform continuous testing and provide documented source code. Since you already have a working prototype, the development process will be faster because we can improve and stabilize the existing design instead of starting from scratch. I would be happy to discuss your current prototype, review the wiring diagram, and suggest improvements before we begin. Thank you for considering my proposal. I look forward to working with you. Best Regards, Naman Pathak

Hi, I don't think the difficult part here is adding the LCD or ESP-01. From your description, it sounds like the bigger issue is making the counting, timing and Wi-Fi work together reliably without one affecting the others. I'd probably start by looking at how the existing sketch is structured before changing anything. If the counting and timing logic are coupled together, or the Wi-Fi routine blocks the main loop, that could explain both the drift and the unstable payloads. Once the core logic is stable, updating the LCD, REST communication, schematic and BOM becomes much easier. A couple of things I'd like to know before starting: 1. Which Arduino board are you using? 2. Is the production count coming from a mechanical switch or a sensor? 3. Is the ESP-01 running AT firmware, or is it programmed separately? I've worked on embedded systems involving Arduino, ESP modules and hardware integration, so this is the kind of debugging and firmware work I'm comfortable with.

Clean LCD UI and full documentation for your manufacturer 4. 48-hour test report to prove accuracy I can start the moment the prototype arrives. Proposal: 6500 INR for 3 milestones, delivered in 7days. Let's get this device ready for production. Thanks, Luc

@vishnu0c0r

Hi, Your project is a good match for my experience in embedded hardware and firmware development. I help take prototypes from "mostly working" to reliable, production-ready systems. I can help you with: • Cleaning and restructuring the Arduino code for stable counting and timing • Improving the LCD interface with clear, operator-friendly information • Implementing reliable ESP-01 Wi-Fi communication with automatic reconnection and REST API support • Reviewing and updating the schematic and BOM for manufacturing • Supporting testing and debugging through quick firmware iterations using your prototype Since you'll be shipping the hardware, I can debug against the actual device rather than making assumptions, which usually leads to a more reliable result. Before starting, I'd like to know: • Which Arduino board is being used? • What LCD module is installed? • Is the schematic available in KiCad, Eagle, EasyEDA, or only as a wiring diagram? I focus on writing clean, well-documented code that's easy to maintain and providing practical solutions suitable for production. I'd be happy to discuss your prototype and get started immediately. Best regards, Vishnu CR Embedded Labs

@joseguillerm22

Hello, as an Electronic and Automation Engineer with extensive experience in firmware development and embedded systems, I have carefully reviewed your project requirements for the industrial counter and timer system. I understand that your current prototype is facing logic drifts and Wi-Fi instability issues. My approach will focus on developing clean, non-blocking Arduino code to ensure simultaneous counting and timing accuracy. I will implement a reliable Wi-Fi routine for the ESP-01 module, featuring automatic reconnection and stable data transmission to your REST endpoint. Additionally, I will provide a clear, easy-to-read LCD interface, update the schematic and BOM for manufacturing, and deliver a comprehensive test report confirming accuracy and uptime after a 48-hour continuous run.

@manis341

Hi, I specialize in embedded C and industrial automation. I have built similar robust counting mechanisms (such as digital deep borewell rod counters) where missing a count is unacceptable and parallel timing is critical. The logic drift you are experiencing is almost certainly due to blocking functions (like delay()) or unhandled interrupts. I will resolve this by rewriting the core architecture: Hardware Interrupts: To handle the industrial counter reliably without missing a single trigger. Non-blocking State Machine: Using millis() for parallel timing and to manage the ESP-01 UART payloads. This ensures the Wi-Fi routine automatically reconnects and handles REST API POSTs without halting the counter. Hardware Docs: I will provide a clean, updated schematic and BOM ready for your contract manufacturer. Since you are available to flash and test revisions on the same day, we can begin immediately without waiting for the physical prototype to be shipped, accelerating the timeline. I will guide you through the 48-hour continuous uptime test to verify the ±1 in 10,000 accuracy. Let's discuss your REST endpoint details and lock in the milestones. I am ready to start. Best regards, Bioz Innovation

@Radebabic

Hi, I can help clean up the Arduino counter/timer firmware and make the ESP-01 REST publishing reliable. I would focus on: - stable simultaneous count + elapsed-time logic - clear LCD display for count, timer and Wi-Fi state - ESP-01 UART reconnect/retry handling - clean REST payload format and documented config - updated wiring notes/BOM and a 48-hour test checklist you can run on the current prototype Since the hardware is already assembled, we can work from your current sketch + wiring diagram, then send revisions for you to flash and verify. One question: should the REST payload be sent on every count event, on a fixed interval, or both?
