This project is a sound sensor-based automatic valve actuator project-Designed for Ghana Water Limited Jeduako_Booster_Station # Automatic_Valve_Actuator_Project The information below is the Arduino description for a sound sensor-based automatic valve actuator project # Sketch Development Using the Arduino IDE, the program code was developed by first including the necessary libraries for the LCD, stepper motor, and buzzer. These libraries provide pre-defined functions and methods essential for controlling each component effectively, streamlining the coding process and ensuring reliable communication with the hardware. Following the library inclusions, I declared a series of global variables that would be used throughout the program. These include pin assignments for key hardware components such as the sound sensor, emergency stop button, status LEDs, valve actuator, stepper motor, and buzzer. Additional variables were also defined to configure the LCD (including its I2C address, number of columns, and rows), as well as to store dynamic values such as detected sound levels, rotation count, and current system status. The next phase involved creating and defining core control functions and logic blocks. These functions handle system behavior during both the setup() and loop() stages of program execution, enabling initialization, user interaction handling, and real-time control of the actuator system. Finally, we implemented the following key control instances to govern system behaviour: i. Instance for starting up the circuit and the motor: The circuit startup is controlled via an ON/OFF switch, while the motor is controlled via sound trigger or the push button. ii. Instance of delay prior to system rotation: This delay matches the pump-set acceleration time, allowing the system to stabilize before engaging the valve actuator. iii. Instance of emergency interrupt function: used to trigger emergency interruptions based on critical conditions or user input, ensuring safety and controlled halts in operation. iv. Instance to control LED: LEDs are used to visually indicate system states: blu …
