Hi, I am an embedded systems engineer with over 16 years of experience developing Arduino-based control systems and taking consumer products from concept through production, including firmware support and hardware bring-up. I understand the required boiler logic: MAX6675 temperature monitoring, three-position shutter control through limit switches, pump hysteresis based on boiler and tank temperatures, over-temperature cooling and alarm acknowledgement, flue fan control, status LEDs, and the 128×64 LCD display. I would implement this as a clear non-blocking state machine with sensor-fault detection, temperature hysteresis, safe startup states, timeout protection for shutter movement, and documented pin assignments. I will provide the complete Mega 2560 firmware, wiring guidance, configuration comments, and support while you test it on the equipment. One point to confirm: does the geared motor rotate continuously in one direction, with Relay 1 powering it until the selected microswitch is reached, and is Relay 4 intended for the flue fan? My quote is AUD 300. I would be glad to discuss the wiring and operating sequence with you before finalising the firmware.

Hi Daryl, I've gone through your wood-fired boiler control system in detail, and this is exactly the kind of embedded automation project I specialize in. With 15+ years working on Arduino/ARM-based control systems, I can confidently handle your Mega 2560 setup with the MAX6675 thermocouple modules, the 4-relay board, and the 128x64 Duinotech dot matrix LCD. Your logic temperature-banded air shutter control (open/half-open/closed via 3 micro-switches), the storage tank pump hysteresis (68°C–72°C), the cold-water safety cooling stage with a flashing LED, and the flue fan tied to shutter position is a well-defined state machine, and I'll implement it cleanly in C/C++ using the Arduino IDE with clear, commented code so you (or anyone else) can follow the logic later even without a programming background. My approach: I'll map all your I/O pins exactly as specified (relays on 50-53, LCD on 11-13, status LEDs on 21-27, etc.), build a non-blocking state machine (no delay() blocking, so the LCD, thermocouples, and switches all stay responsive), add debounce handling for the micro-switches, and test each temperature threshold and relay transition individually before final integration. I'll also add basic safety fallbacks (e.g., sensor fault detection on the MAX6675) since this controls a live fire and pressurized water system. For the full firmware development, testing, and documentation, my quote is USD 350, with delivery in 7-10 days.

Hi there, I read your offer carefully and understand that you need Arduino Mega 2560 firmware for a wood-fired boiler controller using two MAX6675 thermocouples, a 128×64 LCD, relays, microswitch position feedback, pump control, fan control, warning LEDs, and reset/acknowledge logic. I can develop a clean Arduino sketch, organize the temperature thresholds, relay logic, LCD display, microswitch stop conditions, LED indicators, alarm flashing, and safety interlocks. I can also provide a wiring diagram, pin map, parts list review, and setup/testing instructions. My experience with Arduino, embedded C/C++, sensors, relay control, LCD displays, temperature systems, and practical electromechanical control fits this project well. Since this involves 240VAC and boiler safety, I will design the logic carefully with isolation, fail-safe states, and clear testing steps in mind. Just send me a message and we can review the full wiring and confirm the final control sequence. I can quote in USD after checking the exact scope. Best regards, Samuel Tshibangu

I will implement reliable motor control logic using micro switch inputs to manage the air shutter positions and integrate the 128x64 LCD to display real-time boiler and storage tank temperatures. Additionally, I will program LED indicators and fan/pump control to ensure seamless automation and safety. If you want high-quality results, please do not hesitate to contact me.

@codeandcommand

Is your board driving the boiler through relays, or straight PWM to a damper motor? A Mega 2560 with a 128x64 display can absolutely handle temp probes, draft control, and safety cutoffs, I just need to know your sensor setup before locking numbers. Can start today. These numbers are based on the post as written, we will refine them once we talk through the full wiring. Let me know and I will send a plan.

@alluankit01

Hi Daryl, I can develop the Arduino Mega 2560 control program for your wood boiler system, including thermocouple readings, relay logic, LCD display output, pump control, fan control, shutter position logic, LEDs, and alarm reset handling. The best solution is to structure the code around clear temperature thresholds, hysteresis for the tank pump, microswitch inputs for shutter stopping, relay outputs on pins 50–53, LED status outputs, and a simple 128x64 LCD screen showing boiler and stored tank temperatures. I’m comfortable with Arduino Mega, MAX6675 thermocouples, relay control, LCD modules, microswitch logic, boiler/pump automation, safety interlocks, timing logic, and clean commented code. Deliverables include: * Arduino source code * Boiler jacket temperature control * Storage tank pump logic * Air shutter open/half/closed logic * Fan relay logic * Over-temperature cooling relay * Flashing LED alarm with reset switch * LCD temperature display * Pin mapping comments * Setup/testing notes For 240VAC motor/pump wiring, final electrical connection should be checked by a qualified electrician. I’ll focus on reliable, readable control code that matches your described operation. Best regards Ankit

@Webslinger01

Daryl, this is a proper control system you've designed — multiple temperature zones, a 3-position motor, and a pump that needs hysteresis logic. I've done plenty of Arduino firmware for heating systems, so I can see exactly how this needs to be structured. → I'll build the full state machine: fire control, pump cycling between 72/68°C, and the cooling water at 90°C → I'll wire up the LCD, all LEDs, and the flashing alarm with the momentary switch to reset it → Around $250 AUD for the complete sketch, delivered in 2 days, tested against your logic I'll make the code clean and commented so you can tweak temperatures yourself later. Happy to chat if you want to go through the details first.

@miguelcen64

Hello Daryl, I understand your boiler control project and can develop the Arduino Mega 2560 program for the full logic you described: air shutter positioning using relays and microswitch stop points, boiler and storage tank temperature control via MAX6675 thermocouples, pump hysteresis, over-temperature cooling, alarm LED flashing with manual reset, fan control linked to shutter position, status LEDs, and the 128x64 LCD temperature display. I can also structure the code clearly so it is practical to maintain and test on your hardware setup. Safety-oriented logic and reliable state handling will be important for a system controlling heat, water flow, and mains-connected equipment. I’d be happy to deliver clean Arduino code with pin mapping based on your specified I/O numbers. Regards, Miguel

@shenglin0617

Hi Daryl, Your logic is clear to me. Mega 2560, ST7920 128x64 in parallel mode (PSB to GND, RS/RW/E on 11/12/13), two MAX6675 sharing SPI with separate CS, relays on 50 to 53. Shutter: relay1 runs the motor, stopped by the switch on IO2 (0-83C), IO3 (83-85C) or IO4 (85-90C). Pump relay2 on at 55C boiler, tank off at 72C, on again at 68C. Relay3 cooling water 90-110C with 1s flash LED on pin 20, latched until the button on pin 30. Relay4 fan follows open and half only. LEDs 21 to 27, BOILER and STORED on the LCD. I will also add switch debounce, a motor timeout if a limit switch is missed, and a thermocouple fault check so the shutter never sits open on a bad reading. On a wood boiler that matters. I design hardware in Altium too, so later I can give you a small plug-in shield to replace jumper wires, the usual failure point in a hot boiler room. Commented code, a wiring sheet, and support until it runs on your machine. Price in AUD. Regards, ShengLin Gu.
