Pin Configuration

IR OBSTACLE SENSOR MODULE Documentation
Pin Description:
The IR Obstacle Sensor Module has 3 pins, which are described below:
1. VCC (Power Supply Pin)
Function: Power supply input for the module
Voltage: Typically 3.3V to 5V (dependent on the specific module)
Connection: Connect to the positive terminal of a power source (e.g., battery, voltage regulator, or microcontroller's VCC pin)
2. GND (Ground Pin)
Function: Ground connection for the module
Connection: Connect to the negative terminal of a power source (e.g., battery, voltage regulator, or microcontroller's GND pin)
3. OUT (Output Pin)
Function: Output signal indicating the presence or absence of an obstacle
Signal: Digital signal (HIGH or LOW)
Logic:
+ HIGH (typically 3.3V or 5V): Indicates an obstacle is detected
+ LOW (typically 0V): Indicates no obstacle is detected
Connection: Connect to a digital input pin of a microcontroller, Arduino, or other compatible devices to read the sensor output
Connection Structure:
To connect the IR Obstacle Sensor Module to a microcontroller or Arduino board, follow these steps:
1. Connect the VCC pin of the sensor module to the VCC pin of the microcontroller or Arduino board.
2. Connect the GND pin of the sensor module to the GND pin of the microcontroller or Arduino board.
3. Connect the OUT pin of the sensor module to a digital input pin of the microcontroller or Arduino board (e.g., D2, D3, etc.).

Code Examples:

### Example 1: Basic Obstacle Detection using Arduino

In this example, we will use the IR Obstacle Sensor Module with an Arduino board to detect obstacles and turn on an LED when an object is within range.

```c
const int sensorPin = 2;  // IR Obstacle Sensor Module output pin
const int ledPin = 13;    // LED pin

void setup() {
  pinMode(sensorPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop() {
  int sensorState = digitalRead(sensorPin);
  if (sensorState == HIGH) {  // Obstacle detected
    digitalWrite(ledPin, HIGH);
  } else {
    digitalWrite(ledPin, LOW);
  }
  delay(50);  // Debounce interval
}
```

### Example 2: Implementing a Simple Line Follower Robot using Raspberry Pi

In this example, we will use the IR Obstacle Sensor Module with a Raspberry Pi to create a simple line follower robot. The sensor will detect the line and control the robot's movement.

```python
import RPi.GPIO as GPIO
import time

# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
sensor_pin = 17  # IR Obstacle Sensor Module output pin
left_motor_fwd = 23
left_motor_bwd = 24
right_motor_fwd = 25
right_motor_bwd = 26

GPIO.setup(sensor_pin, GPIO.IN)
GPIO.setup(left_motor_fwd, GPIO.OUT)
GPIO.setup(left_motor_bwd, GPIO.OUT)
GPIO.setup(right_motor_fwd, GPIO.OUT)
GPIO.setup(right_motor_bwd, GPIO.OUT)

while True:
    sensor_state = GPIO.input(sensor_pin)
    if sensor_state == GPIO.HIGH:  # Line detected
        # Move forward
        GPIO.output(left_motor_fwd, GPIO.HIGH)
        GPIO.output(right_motor_fwd, GPIO.HIGH)
    else:
        # Stop and turn
        GPIO.output(left_motor_fwd, GPIO.LOW)
        GPIO.output(right_motor_fwd, GPIO.LOW)
        time.sleep(0.5)
        GPIO.output(left_motor_bwd, GPIO.HIGH)
        GPIO.output(right_motor_bwd, GPIO.LOW)
        time.sleep(0.5)
        GPIO.output(left_motor_bwd, GPIO.LOW)
        GPIO.output(right_motor_bwd, GPIO.HIGH)
        time.sleep(0.5)
```

Note: In this example, you need to connect the IR Obstacle Sensor Module to the Raspberry Pi's GPIO pins and the motor driver IC to control the robot's movement.

Troubleshooting Tips:

Ensure the sensor module is properly connected to the power supply and the output pin is connected to a digital input on your microcontroller.
 Adjust the detection range by adjusting the sensor's infrared LED angle or the object's surface reflectivity.
 Use a debouncing mechanism to prevent false triggers due to noise or multiple reflections.
