⚙️ Working Principle:

The IR LED emits infrared light, which reflects off nearby objects and is detected by the IR receiver. The receiver converts the infrared light intensity into an electrical signal that can be read by microcontrollers. This makes it ideal for obstacle detection, line tracking, or signal communication.

It can also be used in remote control systems, where the IR LED sends modulated signals (like 38kHz), and the receiver decodes them into readable data for Arduino or Raspberry Pi.

⚙️ Applications & Use Cases:

• 🤖 Robotics – Obstacle detection and line-following robots.

• 📡 Remote Control Systems – IR-based wireless signal transmission.

• 🧠 IoT Projects – Smart IR-controlled devices and automation systems.

• 💡 Security Systems – Motion sensing and object detection.

• ⚙️ Electronic Prototyping – For learning IR communication with Arduino accessories.

• 🏠 Smart Home Devices – IR-controlled lights, fans, or appliances.

⚙️ Precautions:

• ⚠️ Avoid direct sunlight or strong light sources to prevent interference.

• ⚠️ Always use a current-limiting resistor with the IR LED.

• ⚠️ Maintain proper alignment between transmitter and receiver for best performance.

• ⚠️ Keep IR components clean and dust-free for optimal detection.

• ⚠️ Do not exceed recommended voltage and current ratings.
