/*In this code:
We define turbidityPin as the analog pin connected to the output of the turbidity sensor.
voltageReference is set to 5.0V, which is the reference voltage of the Arduino Uno.
In the setup() function, we initialize serial communication.
In the loop() function, we read the raw analog value from the turbidity sensor using analogRead().
We convert the raw analog value to voltage by scaling it based on the reference voltage (5.0V) and the ADC resolution (1023 steps).
You need to implement the mapVoltageToTurbidity() function to map the voltage value to turbidity level using your calibration values. This function should return the corresponding turbidity level based on the voltage.
We print the turbidity value to the Serial Monitor with the name of the sensor.
Adjust the delay as needed to control the sampling frequency.
Replace "SensorName" with the actual name of your turbidity sensor. Additionally, you'll need to calibrate the sensor and adjust the mapping function accordingly to obtain accurate turbidity readings.
