Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with a TDS Sensor, a PH Meter, and a Servo motor. The Arduino UNO reads analog signals from the TDS Sensor and PH Meter, and controls the Servo motor through a PWM signal.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where you place the main logic that runs repeatedly.
