: Bluetooth Controlled Water Pump

To control a water pump wirelessly using Bluetooth. When the button is pressed, the Arduino sends an “ON” command through Bluetooth to control the pump.

1. The Arduino continuously checks the push button.
2. When the button is pressed, the Arduino activates the pump.
3. Pins D6 and D7 control the pump through the driver circuit.
4. The Bluetooth module can be used to communicate the pump's status.
5. The pump should be powered from a suitable external supply rather than directly from the Arduino.

This project demonstrates how an Arduino Nano can control a water pump using digital output pins and Bluetooth communication. It provides a simple foundation for building a wireless or IoT-based pump-control system.
