Master IR Control! Complete IR Transmitter & Receiver Kit for Arduino, Learn Remote Signals & Build Smart Devices.

Product Description:
Unlock the world of wireless communication! This complete IR kit pairs a 38KHz transmitter and a high-sensitivity receiver, providing everything you need to send and interpret infrared signals. Perfect for learning how remotes work, building custom controllers for smart home devices, or adding remote control to your Arduino robots and cars.

Key Features & Benefits:

Complete Matched Pair: Includes one transmitter and one receiver module, factory-matched to work seamlessly together. This saves you the hassle of sourcing compatible components separately and gets your project running faster.

Standard 38KHz Compatibility: Operates at the universal frequency used by most TV, AC, and DVD remote controls. This makes it an ideal educational tool for learning and decoding common infrared protocols.

Long-Range & High-Sensitivity: The receiver can detect signals from up to 10 meters away, even at angles. This ensures reliable performance in real-world applications like remote-controlled cars and smart switches.

Digital Output & Easy Interface: The receiver outputs a clean, demodulated digital signal, which can be directly read by your Arduino’s digital I/O pins. This simplifies wiring and coding, making it beginner-friendly.

🚨 Important Notes / How to Use:

🔧 REQUIRES CODING FOR DECODING: The receiver module 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 light requires a relatively clear path between the transmitter and receiver. Solid obstacles, bright sunlight, or other strong IR light sources can significantly interfere with or block the signal.

⚡ 5V OPERATION: Both modules are designed for a 5V power supply. Connecting them to 3.3V systems may result in unreliable operation or reduced range.

🔄 TRANSMITTER LIMITATION: The transmitter is for sending coded signals, not for continuous illumination. It must be pulsed at 38KHz (using code) to be recognized by the receiver.
