📡 IR Remote Control (Transmitter)

📌 Description

An IR remote control sends signals using infrared light. Each button has a unique code that the receiver can read. These codes can be expressed as raw hexadecimal values or simplified hex‑commands. Using hex‑commands makes programming easier and cleaner.

🎯 Use

In our projects, the IR remote is used to:

• Control robots wirelessly.
• Send commands like forward, backward, left, right.
• Trigger actions such as turning LEDs on/off or changing modes.

👉 Think of the IR remote as the robot’s wireless joystick — it sends instructions with button presses.

🖥️ Button Codes (Hex‑Command)

Here’s the simplified mapping of buttons to hex‑commands:

✅ Conclusion

• Each button on the IR remote has a unique hex‑command.
• Using these codes, you can program your robot to respond to button presses (e.g., move forward when pressing “Up”).
• The hex‑command format is shorter and easier to handle than raw codes, making your code cleaner.
