+# AutoFilm-ESP32 README
+
+## Overview
+
+AutoFilm-ESP32 is an automated film processing machine designed to handle the development of photographic film using a Kindermann style stainless steel tank. The device utilizes an ESP32 microcontroller, NEMA-17 stepper motor, DS18B20 temperature sensor, and a 2004 type LCD with I2C interface. The software allows for precise control of the development process, including rotation patterns and agitation timings.
+
+## Features
+
+- **Automated Film Processing**: Automates the film development process, reducing the need for manual intervention.
+- **Customizable Sequences**: Define and adjust development sequences for various film types and processes.
+- **User Interface**: Simple and intuitive interface with a keypad and LCD display.
+- **Persistent Settings**: Upcoming feature to store and manage processing parameters directly on the device without recompilation.
+
+## Hardware Components
+
+- **Microcontroller**: ESP32
+- **Motor**: Waterproof NEMA-17 stepper motor
+- **Temperature Sensor**: DS18B20
+- **Display**: 2004 type LCD with I2C interface
+- **Mechanical Parts**: 
+  - 8mm brass rods
+  - Plastic bearings
+  - 3D printed idlers, gears, and chassis
+  - Stainless steel tank (Kindermann style)
+
+## Software Structure
+
+### Main Components
+
+1. **devSequences.cpp**: Defines the processing sequences for various development processes. Each sequence includes:
+   - Ideal processing temperature
+   - Upper and lower temperature bounds
+   - Rotation patterns
+   - Agitation times for each step
+
+2. **Keypad Navigation**: Use the keypad to adjust processing times for each step. Left and right buttons facilitate this adjustment.
+
+### Future Improvements
+
+- **Persistent Parameter Storage**: Move processing parameters to files for in-device storage and modification without recompilation.
+- **Extended Customization**: Enhance user interface to allow for more detailed customization of development sequences.
+
+## Getting Started
+
+### Prerequisites
+
+- ESP32 development environment set up
+- Required hardware components assembled and connected as per the schematic
+- Water bath with temperature control (e.g., sous vide heater)
+
+### Installation
+
+1. Clone the repository:
+   ```bash
+   git clone https://git.i3omb.com/gronod/AutoFilm-ESP32.git
+Open the project in your preferred IDE (e.g., Arduino IDE, PlatformIO).
+Configure the project settings, including Wi-Fi credentials if necessary.
+Upload the code to the ESP32 microcontroller.
+
+###Usage
+1. Setup:
+
+ - Ensure the development tank is clean and dry.
+ - Prepare the water bath and set the desired temperature using a sous vide heater or another closed-loop temperature control device.
+ - Submerge the development tank in the water bath.
+
+2. Initialization:
+
+ - Power on the device and wait for the initial setup to complete.
+3. Sequence Selection:
+
+ - Select the desired development sequence from the options provided.
+4. Processing Steps:
+
+ - For each processing step, follow these instructions:
+  1. Add Chemistry: Fill the tank with the required volume of the developing chemical.
+  2. Start Step: Begin the step by pressing the appropriate button on the keypad. The device will rotate and agitate as per the defined sequence.
+  3. Monitor Temperature: Ensure the water bath maintains the correct temperature range.
+  4. Drain Chemistry: At the end of the step, drain the developing chemical from the tank.
+  5. Rinse and Repeat: Repeat the process for each subsequent step, adding and draining the appropriate chemicals as needed.
+
+5. Completion:
+
+
+ - Follow standard procedures to dry the film.
