Project description:
"I want to develop a semi-automatic cooking machine prototype using an ESP32 microcontroller that automates a 12-slot Geneva wheel–based ingredient carousel.

The system should execute a recipe sequence automatically based on data stored in a CSV file on an SD card and be controllable via a Nextion display or mobile interface (through ESP32 Wi-Fi AP mode, no Internet required).



Functional Requirements:

1️⃣ Mechanical Overview

12-slot Geneva wheel (600 mm diameter) driven by a stepper motor for indexing.

At each station, the machine performs ingredient-handling tasks such as gripping, vibrating, flipping, and dropping ingredients into a pan.



2️⃣ Electronic Controls

Main controller: ESP32 Dev Board

Motors and Actuators:

1 × Stepper Motor (for Geneva indexing)

3 × Servo Motors (MG996R or MG90S):

Servo 1 → Rotate Arm 90°

Servo 2 → Flip Ingredient Container 180° (invert)

Servo 3 → Open/Close Pan Lid

1 × DC Motor → Rotate cooking pan

1 × Electromagnetic Solenoid → Grip/Release container

1 × Encapsulated Vibrator → Vibrate ingredient container

Relays/SSR Modules for:

DC motor power ON/OFF

Induction heater ON/OFF

Exhaust fan ON/OFF optional

Buzzer → Audible indication and process alerts

SD Card Module → To read operation sequence from CSV file



User Interface:

Option A: Nextion Display (UART interface)

Option B: Mobile/Web UI (ESP32 AP Mode, no internet" (client-provided description)
