Hello, I can write this micropython code to detect this pulse and do the blinking of LED and push button integrated. I can suggest the optoisolator circuit aswell.

@PathumSudarshana

The 24 V kick-out pulse will be safely handled using a small optocoupler (PC817 or similar) with a single series resistor. This isolates the ESP32 completely and avoids any grounding or noise issues. The opto output connects to an ESP32 GPIO using the internal pull-up. The MicroPython code is intentionally minimal: the ESP32 waits idle for the pulse, starts blinking a single LED as soon as it’s detected, and keeps blinking until a momentary push-button is pressed. On that press, the LED turns off and the system returns to its waiting state. No extra libraries, no unnecessary complexity. I’ll provide the MicroPython file with clear comments, a simple wiring diagram, and a short read-me so you can flash and test everything in minutes.

Hello, I hold a Master’s degree in Automatic and Systems Engineering and have solid hands-on experience with embedded systems, ESP32, MicroPython, and industrial I/O interfacing (24 V signals, opto-isolation, GPIO safety). Your Epson TM-T82IIIL cash-drawer project is a perfect fit for my background. I will deliver a lean, reliable solution that safely detects the 24 V kick-out pulse and drives the required LED logic exactly as specified. I will deliver: • A clean MicroPython (.py) program for ESP32 with clear inline comments (no external libraries). • A minimal wiring diagram showing opto-isolation (recommended for 24 V POS signals), ESP32 GPIOs, LED, and reset push-button. • A short README explaining flashing, wiring, and quick testing so you can be up and running in minutes. Technical approach: • Optocoupler-based 24 V → 3.3 V isolation for electrical safety and noise immunity. • Edge detection to catch short pulses reliably. • Deterministic LED blinking until user reset via push-button. • Simple, maintainable code aligned with MicroPython best practices. I’ve previously designed ESP32-based monitoring and signaling systems interfacing with industrial and commercial hardware, ensuring robustness and clarity.

@hancho6319

Thank you for the clear specifications. I will develop a lean, robust MicroPython program for your ESP32 to monitor the Epson printer's 24V cash drawer pulse. For safety and reliability, I will design the interface using a 4N35 optocoupler to isolate the 24V signal, protecting the ESP32. The firmware will use an interrupt to detect the pulse, trigger a blinking LED state, and monitor a GPIO pin for the button press to return to idle. I will deliver the fully commented .py file, a clear wiring diagram (showing the optocoupler circuit, LED with resistor, and button), and a concise README with flashing instructions. The solution will use only core MicroPython libraries for maximum portability

Hello, I’m an embedded systems engineer with hands-on experience using ESP32 and MicroPython for simple, reliable I/O control and signal conditioning. Your requirement is very clear: detect a 24 V pulse from the Epson cash-drawer port, safely translate it to logic level, and trigger a blinking LED that latches until a manual reset button is pressed. This is a straightforward, robust state-machine problem well suited to MicroPython. I will deliver: • A lean MicroPython script using GPIO interrupts/timers (no external libraries) • Safe input conditioning via opto-isolation or resistor divider (clearly documented) • Simple LED blink logic with push-button reset • Minimal wiring diagram + short README for fast flashing and testing The key focus will be electrical safety and deterministic behavior—no false triggers, no extra complexity. Best regards,

@VictorAbreu97

I can help you with this using a very simple and reliable ESP32 + MicroPython setup. I’ve worked on many small control and indicator projects like this, especially where higher voltages need to be safely interfaced with microcontrollers. I’ll write a small MicroPython script that watches the 24 V cash-drawer pulse, safely converts it to a logic-level signal, and starts blinking an LED as soon as the drawer opens. The LED will keep blinking until you press a push-button, at which point it turns off and the ESP32 goes back to waiting. Nothing extra, no unnecessary features. I’ll provide: Clean, well-commented MicroPython code A simple wiring diagram showing the ESP32 pins, LED, button, and a safe input method (opto-isolator or divider) A short README so you can flash and test everything quickly The solution will be lightweight, easy to understand, and use only standard MicroPython features. If you want, I can also suggest the safest input option depending on how noisy the 24 V line is.

@Lsstudio1228

We understand you want a lean MicroPython program for ESP32 to detect your Epson TM-T82IIIL’s 24V pulse, and manage LED blinking until reset with a push-button.
