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)
