17-Key IR Remote Control with Directional Pad (CR2025 Battery)

Description

The 17-Key IR Remote Control is a compact, ultra-thin infrared transmitter specifically laid out for intuitive navigation and control. Operating on the standard 38kHz carrier frequency, it is highly compatible with nearly all standard IR receiver modules (such as the TSOP1838) and popular microcontrollers like Arduino, ESP32, and Raspberry Pi.

Unlike standard media remotes, this specific model features a highly practical layout tailored for maker projects. It includes a full 0-9 numeric keypad, designated * and # function buttons, and a prominent blue directional pad (D-pad) with a central red "OK" button. This makes it the absolute perfect choice for driving custom robotics chassis or navigating through LCD menu systems. Now available at Tomson Electronics, this complete package includes a fresh CR2025 lithium coin cell battery pre-installed, ensuring your build is ready to operate right out of the box.

• Smart Home & Lighting: Assigning specific numbered keys to different smart relays, LED lighting modes, or automated systems.
• Security Systems: Using the numeric keypad to input simple PIN codes for custom Arduino-based lock boxes or alarm systems.

Frequently Asked Questions (FAQ)

Q: Is the battery included, and is it replaceable?
A: Yes, the remote comes with a CR2025 3V lithium coin cell battery installed. It can be easily replaced by sliding out the battery tray located at the bottom edge of the remote.

Q: Do I need a specific receiver for this remote?
A: You will need an infrared receiver module that operates at 38kHz, which is the industry standard for most hobbyist electronics. The TSOP1838 or VS1838B IR receiver diodes are perfectly suited for decoding this remote's signals.

Q: How do I program the different buttons?
A: When pressed, each button emits a unique hexadecimal code via infrared light. By using an IR receiver and a standard library (like `IRremote` for Arduino), you can easily read these hex codes and write simple `if/else` or `switch` statements in your code to trigger different actions (e.g., if the "Up Arrow" hex code is received, turn both motors forward).
