🛠️ Step 1: Wiring the Circuit

IR Sensor to Arduino:

OUT → Pin 2 (Arduino Digital)
VCC → 5V
GND → GND

💡 Place your hand or any object in front of the IR sensor to trigger the output signal.

💻 Step 2: Upload the Arduino Code

Open Arduino IDE.
Select your board: Arduino Uno
Upload the IR detection sketch from the GitHub repo.

🐍 Step 3: Setup PC Communication

You’ll use a Python script to monitor the Arduino’s serial output and open a URL when motion is detected.

Install Python on your PC (if not already installed).
Use VS Code or any Python IDE to open the provided script.
Install required packages:

Run the Python script. It listens to the Arduino and opens a website when a signal is received.

🌐 Step 4: Test It Out!

With everything running, move your hand in front of the IR sensor.
The Arduino sends a signal via USB.
The Python script receives the signal and opens the designated URL in your default browser.

✅ Try changing the URL in the Python script to link to your favorite website or automation dashboard!

✅ Result

You’ve just built a gesture-controlled web launcher! Perfect for kiosk setups, automation triggers, or just showing off cool tech tricks to friends.
