The Microwave Oven Control System is a microcontroller-based application designed to manage the operations of a microwave oven. This system includes a state machine that responds to user inputs, sensor readings, and system components. Whether you're building a new microwave oven or enhancing an existing one, this project provides a solid foundation for implementing the control logic.
Note: This project can be fully tested, run, and developed using Proteus simulation software. There is no need for physical hardware setup to get started. Proteus provides a virtual testing environment that allows for the complete simulation of the microwave oven control system, including all electronic components and microcontroller interactions.
The project is open source and you can use it for your own projects.
-
State Machine Management:
- The heart of the system is a robust state machine that governs the microwave's behavior.
- Transitions between states occur based on user actions (start,stop) and sensor events (door open/close, food exist/not_exist, timer adjused/not).
-
User Interface Interaction:
- The system interacts with users through a keypad.
- Users can set the cooking timer, start/stop the microwave, and receive prompts on the display.
-
Display Updates:
- The display provides status information.
- It shows the current state ("Door Opened", "Running", "Paused",e.g.) and prompts users as needed.
-
System Control Components:
- The system manages various components:
- Heater: Responsible for cooking the food.
- Motor: Controls the turntable.
- Lamp: Illuminates the microwave cavity.
- Activation and deactivation of these components are handled by the state machine.
- The system manages various components:

This microwave oven control system primarily involves these main user operations:
Simulation Video: This is a simulation video using proteus that shows all system operations.
-
Setting the Timer:
-
Use the keypad to input the desired cooking time.
-
The display will guide you through this process.
-
Setting timer from keypad:
-
Reseting timer by pressing Stop_PB:
-
-
Starting the Microwave:
-
Close the microwave door,so you don't see this message.
-
Put food inside the microwave,so you don't see this message.
-
Adjust the timer (min:sec) from keypad,so you don't see this message.
-
If all above conditions are true ,the system transitions to the "Running" state.The heater and motor activate, and the display updates accordingly.
-
-
Pausing the Microwave:
-
If the Stop_PB is pressed,the system transitions to the "Paused" state.
-
If the door opened.
-
This message will apear.
-
Then system transitions to the "Paused" state.
-
-
If the no food inside.
-
This message will apear.
-
Then system transitions to the "Paused" state.
-
-
-
Starting after Pausing:
-
If the Start_PB is pressed,the system transitions to the "Running" state again.
-
But the door must be closed and the food must be inside,so you don't see these messages and the system remaining in pause state.
-
-
Stop the Microwave:
-
Press the Stop_PB once the system transitions to Pause state and once again the Timer resets then the system transitions to the wellcome page.

Clone this repository to your local machine:
git clone https://github.com/abd-elarhman/Microwave-Oven.git
To develop the project, you need to:
- YOU MUST HAVE Microchip studio installed on your computer.
- Open the (01-Microchip-Studio-Project\Atmega32) directory.
- Open the [Microwave.atsln] file and it will open with Microchip Studio.
- You can build the project by clicking on F7 key on keyboard.
NOTE: The code is documented as much as possible. Hope you will understand the code.
To simulate the project, you need to:
- YOU MUST HAVE Proteus installed on your computer.
- Open the (04-simulation/) directory.
- Open [Microwave_simulation.pdsprj] file and it will open with Proteus.
- The simulation works as the following:
- load the ".hex" or ".elf" file on the microcontroller in the simulation and run.
- load "Atmega32.hex" file when you build the project from microchip studio with Release solution configurations.
..\01-Microchip Studio Project\Atmega32\Atmega32\Release - load "Atmega32.elf" file when you build the project from microchip studio with Debug solution configurations and Enjoy debugging features of proteus.
..\01-Microchip Studio Project\Atmega32\Atmega32\Debug
The Microwave Oven Control System is an ongoing project, and I'm constantly looking to improve and expand its capabilities. Here are some of the enhancements I'm considering for future releases:
- User Profiles: Allowing users to create profiles to save their preferred settings and quickly access frequently used cooking modes.
- Advanced Features: Implementing additional features such as automatic Sleep when it not used.
- Recipe Database: Incorporating a database of recipes with pre-programmed cooking settings for user convenience.
- Real Time OS: implementing the system using RTOS.
Your feedback and contributions are valuable to me. If you have ideas for new features or ways to enhance the system, please feel free to share them by opening an issue or submitting a pull request.
Stay tuned for updates and thank you for your support!
