**Design and Implementation of Automatic Washing Machine Using Verilog**
### Abstract
This paper presents a Verilog-based automatic washing machine control system that automates essential functions like water filling, washing, rinsing, and spinning. It leverages a finite state machine (FSM) for efficient control, ensuring smooth transitions between various washing stages.

# Introduction
The system is built around an FSM that manages the washing process from start to finish. Sensors and user inputs play a key role in ensuring safe and efficient operation. The design emphasizes energy and water efficiency, aligning with modern smart home trends.

##methodology
#### Existing System
- Uses an FSM model where each stage (Idle, Fill Water, Wash, Rinse, Drain) transitions based on inputs.
- Uses binary-coded states for phase management.

#### Implemented System
- Enhanced FSM design with states:
- IDLE: System standby mode.
- READY: Awaits user selection.
- SOAK: Prepares clothes by soaking with detergent.
- WASH (Mode 1, 2, 3):Supports multiple washing intensities for various laundry loads.
- RINSE: Cleans detergent residue.
- SPIN: Extracts water before returning to the IDLE state.

#results
The system was tested across different modes:
- Mode 1, Mode 2, Mode 3: Each successfully handled different laundry loads.
- Cancellation options were verified during different phases.
- State transitions were controlled by the timer and triggered by specific conditions.

#conclusion
The system demonstrated effective FSM-based control over washing machine operations. The modular design enhances adaptability for future improvements, promoting efficient energy and water management.

# Future Scope
- Enhanced Sensors: Adding water-level and temperature sensors.
- Smart Connectivity: IoT integration for remote control and monitoring.
- Improved Error Handling: Fault detection and self-diagnostics.
- Eco-Friendly Features: Advanced algorithms for water and energy conservation.
