Introduction The Smart Cooking System integrates a mobile app with smart seasoning jars that feature built-in scales to simplify cooking. Users manually input the weight of ingredients into the app, which calculates the required seasoning amounts. The jars guide users by lighting up and dispensing precise quantities. Progress is updated on the app and synced with the jars, ensuring an intuitive and seamless cooking experience.
Features
-
Mobile App as a Control Hub:
-
Choose recipes and input ingredient weights manually.
-
View progress updates as you cook.
-
Smart Seasoning Jars:
-
Integrated scales for precise seasoning measurement.
-
LED indicators to guide usage.
-
Wireless communication with the app.
-
Bidirectional Communication:
- The app sends calculated seasoning requirements to the jars.
- The jars update the app once dispensing is complete.
General Look:
System Design
Smart Seasoning Jar Each jar is designed to weigh and dispense seasoning while communicating progress to the app.
Key Features:
- Integrated scale for measuring seasoning output.
- LED light for guidance.
- Wireless communication (e.g., Bluetooth/Wi-Fi).
Sketch:
Workflow
User Input:
- Select a recipe in the app.
- Manually input the weight of the main ingredients. Calculation:
- The app calculates the required seasoning for each jar. Guidance:
- Jars light up to indicate which seasoning to use and how much to dispense. Progress Update:
- Jars notify the app after each step is completed.
System Communication
Communication Workflow App to Jar: Recipe details and calculated seasoning amounts are sent to the jars. Jar to App: Jars update the app with dispensing progress in real time. Diagram:
Detailed Data Flow
Step 1: User selects a recipe in the app and inputs the weight of the ingredients.
Step 2: The app calculates seasoning proportions and sends the instructions to the jars.
Step 3: Jars guide the user by lighting up and dispensing seasoning. Dispensing progress is sent back to the app.

Sensors and Hardware Components
Sensors Load Cell (Weight Sensor):
Used to measure the weight of the dispensed seasoning. Communicates data to the internal microcontroller. Example: HX711 ADC module for weight data precision. Datasheet: HX711 Datasheet
LED Indicators:
Provides visual feedback to users on which jar to use and how much to dispense. Example: WS2812 RGB LED. Datasheet: WS2812 LED Datasheet
Wireless Communication Module:
Ensures communication between jars and the mobile app. Example: ESP32 or ESP8266 for Bluetooth/Wi-Fi connectivity. Datasheet: ESP32 Datasheet
Power Management:
Powers the jars and sensors. Example: Rechargeable Li-Po battery with charging module (e.g., TP4056). Datasheet: TP4056 Datasheet

Questions
What parts does the Magic Seasoning PCB use?
6 parts, built around the ST25R3911B-AQFT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Magic Seasoning PCB KiCad files?
From the Sidiment/Magic-Seasoning repository on GitHub, at the commit this page was made from: the board is PCB/Magic_Seasoning_PCB/Magic_Seasoning_PCB.kicad_pcb and its schematic PCB/Magic_Seasoning_PCB/Magic_Seasoning_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magic Seasoning PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sidiment before reusing the design.
