Product Description：
This is a complete infrared wireless communication kit designed for learning IR principles, cloning remote signals, developing smart home devices, or adding remote control to Arduino projects. Whether you’re a beginner or a developer, this ready-to-use kit helps you quickly enter the world of IR communication.

🚨 Important Notes / How to Use：

Coding Required for Decoding: The receiver only outputs a demodulated digital waveform. To understand specific commands (e.g., volume up, power on), you MUST use an Arduino library (like IRremote) to decode the signal. It does not output pre-decoded command values.

Line-of-Sight Operation: Infrared requires a relatively clear path between transmitter and receiver. Solid obstacles, bright sunlight, or other strong IR sources can interfere or block the signal.

5V Operation Only: Both modules are designed for 5V supply. Connecting to 3.3V systems may cause unreliable operation or reduced range.

Transmitter Must Be Pulsed: The transmitter is for sending coded signals, not continuous light. It must be pulsed at 38KHz (via code) to be recognized by the receiver.
