The Timer-Based Automatic Water Heater project is designed to switch ON and OFF the water heater at preset times automatically. It eliminates the need for manual operation, ensuring hot water is ready when needed while preventing unnecessary electricity usage.

This system uses a microcontroller or RTC (Real Time Clock) module to keep track of time and a relay switch to control the heater. It is widely applicable in homes, hostels, and industries where scheduled heating is required.

Parts Used:

1. Microcontroller (Arduino / PIC / ESP32) – Controls heater operation
2. RTC (Real-Time Clock) Module – Provides accurate timing
3. Relay Module – Switches water heater ON/OFF safely
4. Push Buttons / Keypad – For setting timer values
5. LCD / OLED Display – Shows set time and status
6. Buzzer / LED – Alerts when the heater is ON or OFF
7. Power Supply (Battery/Adapter) – Runs the control circuit
