Summary

This circuit consists of an IR sensor, a Micro Servo 9G, and an Arduino UNO. The IR sensor detects objects and sends a signal to the Arduino UNO, which then controls the Micro Servo 9G based on the sensor input. The Arduino UNO also outputs the status of the object detection to the serial monitor.

Code Documentation

Arduino UNO Code

void setup() 
{
  Serial.begin(9600);
  pinMode(6, INPUT);
  Serial.println("Serial Working");
}

void loop() 
{
  int ss = digitalRead(6);
  if (ss == LOW)
  {
    Serial.println("Object Detected");
  }
  else
  {
    Serial.println("Object Not Detected");
  }
}

• setup(): Initializes the serial communication at 9600 baud rate and sets pin 6 as an input. It also prints "Serial Working" to the serial monitor.
• loop(): Continuously reads the state of pin 6. If the state is LOW, it prints "Object Detected" to the serial monitor. Otherwise, it prints "Object Not Detected".
