Sony CRT Remote Controller

Control a Sony CRT TV using an infrared (IR) LED. It utilizes the IRremote library to send Sony-specific IR signals.

Tested with: KV-29FQ75D, KV-1434M3.

Features:

• Control various TV functions: Power, volume, channel, playback, input source, and more.
• Predefined Sony codes: Includes a comprehensive list of IR codes for common Sony CRT TV functions.
• Custom code support: Send arbitrary IR codes in hexadecimal format.
• Multiple command execution: Send sequences of commands separated by commas.
• Debug mode: Provides feedback on the sent codes for troubleshooting. (Shows which code is sent)
• Interactive menu: Access a menu via the Serial Monitor to list commands, view hex codes, and toggle debug mode.

Hardware Requirements:

• Arduino board (e.g., Uno, Nano, Mega)
• IR LED (Infrared Light Emitting Diode)
• Jumper wires

Wiring:

• IR + : Pin 3 (IR_SEND_PIN)
• IR GND : GND

Software Requirements:

• Arduino IDE
• IRremote library (Install through the Library Manager in the Arduino IDE)

Usage:

1. Upload the sketch to your Arduino board.
2. Open the Serial Monitor (Tools > Serial Monitor) and set the baud rate to 9600.
3. Use the following commands in the Serial Monitor:
   • Numbers 1 to 45: Send the corresponding predefined Sony TV code.
   • l: List all predefined codes with their hexadecimal values.
   • m: Display the command menu.
   • d: Toggle debug mode on/off.
   • 0xXXXX: Send a custom IR code in hexadecimal format (replace XXXX with the code).
   • Multiple commands: Separate command numbers or hex codes with commas (e.g., 1,18,0x290).

Example:

To turn on the TV and then increase the volume:

750,490 

Customization:

• IR_SEND_PIN: Change this constant if you are using a different pin for the IR LED.
• REPEAT_COUNT: Adjust the number of times the IR code is sent for each command.
• DELAY_BETWEEN: Modify the delay between repeated IR code transmissions.
• BIT_LENGTH: This is the bit length used for the Sony protocol. Usually, it should be 12.
• COMMAND_DELAY: Change the delay between multiple commands.
• SONY_CODES: Add or modify IR codes for your specific Sony TV model. You can find code lists online or use an IR receiver to capture codes from your original remote.
