IRB

This project is a Universal IR Blaster built using NodeMCU (ESP8266) and the IRremote library. It enables you to capture, save, and blast infrared (IR) codes with ease through a web-based interface. The system integrates both an IR receiver and transmitter, allowing users to manage and control IR-based devices remotely.

Features

• IR Receiver & Transmitter: Capture IR signals and replay them whenever you want.
• Web UI: Easy-to-use interface for downloading, storing, and blasting IR codes.
• JSON-based Code Storage: IR codes are stored in JSON format, enabling users to save and load codes for later use.
• Customizable: Can be adapted to work with a wide range of IR protocols such as NEC, Samsung, Sony, Panasonic, and more.
• Wi-Fi Support: Wi-Fi functionality powered by ESP8266 to host a local server for web interaction.

Requirements

• Hardware:

  • NodeMCU ESP8266
  • IR Receiver (e.g., TSOP38238)
  • IR LED (for transmitting signals)

• Software:

  • Arduino IDE
  • IRremote library for IR control
  • ESP8266 Board Support in Arduino IDE
  • ArduinoJson library for managing JSON data

Setup & Installation

1. Hardware Setup

• Connect the IR Receiver to the NodeMCU:

  • VCC → 3V3
  • GND → GND
  • OUT → D5 (GPIO pin)

• Connect the IR LED for transmitting:

  • Anode (+) → D6 (GPIO pin)
  • Cathode (-) → GND

2. Arduino IDE Setup

• Install the ESP8266 Board Support in the Arduino IDE via the Board Manager.
• Install the IRremote and ArduinoJson libraries in Arduino IDE:
  • Go to Sketch → Include Library → Manage Libraries.
  • Search for and install IRremote and ArduinoJson.

3. Upload the Code

• Select the correct board (NodeMCU (ESP8266)) and port in the Arduino IDE.
• Upload the provided sketch to the NodeMCU.

4. Accessing the Web UI

• After uploading, the NodeMCU will create a Wi-Fi access point.
• Connect your device to the IRB Wi-Fi network (password: IRHACKED).
• Open a web browser and navigate to 192.168.4.1 to access the web interface.

Usage

Capturing IR Codes

• Point your IR remote at the receiver and press a button.
• The captured IR code will be automatically saved and shown in the web UI as a JSON file.

Storing IR Codes

• IR codes can be saved in JSON format. You can download the captured IR code file for later use.

Blasting IR Codes

• Load the saved JSON IR code(s) to the web UI.
• Select the code you want to blast and click the Blast button to transmit the IR signal to your device.

Stopping Blasting

• Click the Stop button on the web UI to stop blasting the IR code.

Code Breakdown

Key Functions:

• storeCode(IRData* aIRReceivedData): Captures and stores the received IR code into a structured format (IR data).
• sendCode(): Sends the stored IR code using the IR LED, supporting different protocols like NEC, Samsung, Sony, etc.
• handleRoot(): Serves the main HTML page for the web interface.
• handleBlast(): Toggles blasting on or off based on the user request.
• handleLoadCode(): Loads the IR code from the provided JSON data and prepares it for blasting.
• fromIR() and toIR(): Functions that convert between IR code data and JSON format for easy storage and retrieval.

IR Protocols Supported:

• Raw, NEC, SAMSUNG, SONY, PANASONIC, DENON, SHARP, LG, JVC, RC5, RC6, ONKYO, APPLE, BOSEWAVE, LEGO_PF.

Troubleshooting

• Web UI Not Accessible: Ensure that your device is connected to the IRB Wi-Fi network and try accessing 192.168.4.1.
• IR Code Not Captured: Ensure the IR receiver is properly connected and within range of your remote control.
• IR Blasting Not Working: Check the wiring of the IR LED and ensure it is connected to the correct GPIO pin.
