Function: Multi-functional infrared (IR) remote control designed for wireless operation of MP3 player modules, home appliances, and IR-compatible electronic devices.

Technology: Uses infrared signal transmission for reliable, line-of-sight control within a range of up to 8–10 meters.

Compatibility: Works seamlessly with MP3 decoder boards, Arduino IR receiver modules, and other IR-based control systems.

Buttons & Layout: Features a clearly labeled keypad with numeric buttons, playback controls (Play, Pause, Next, Prev, Vol+, Vol–), and function keys for custom programming.

Power Source: Operates on standard coin cell battery (CR2025 or CR2032, depending on model) for long-lasting use.

Applications: Ideal for DIY audio systems, robotics control, IR automation, and learning remote-sensing applications in electronics.

Construction: Lightweight ABS plastic body with soft-touch buttons and wide-angle IR LED emitter for consistent signal coverage.

Ease of Use: Plug-and-play with compatible IR receiver modules; requires minimal coding effort for integration into Arduino and microcontroller projects.

Design: Compact, portable, and durable — perfect for classroom demos, home automation prototypes, and personal electronics setups.
