MyTV Remote Control Infrared Protocol reversed.

MyTV Remote Control Infrared Protocol

Last month I decided to learn a little more about communication protocols, so I picked up the first thing next to me that could send a signal to another device. Near my pc there was the remote control of my television (MyTV). So I set up my Arduino board and acquired the signal sent from the remote control.

Getting Started

Follow "Prerequisites" and "Installing" sections to run the software.

Prerequisites

Things that you need to have to run the code:

• git
• Python 2.7
• Arduino IDE
• Arduino© board or alternatives
• Arduino© Infrared receiver module or Infrared receiver sensor

Installing

Clone the repository

git clone "https://github.com/SamuelePerticarari/Analyze-MyTV-Remote-Control-Infrared-Protocol.git" "Analyze-MyTV-Remote-Control-Infrared-Protocol"

Setup the board

Connect the sensor to the board like that.

Flash the software to the board

1. Connect the board to your laptop.
2. Open Arduino IDE
3. Open "/Analyze-MyTV-Remote-Control-Infrared-Protocol/src/Arduino Project/ReadFromInfraredSensor/ReadFromInfraredSensor.ino"
4. Make sure that board is recognized.
5. Flash software.

Run the Python program

cd "Analyze-MyTV-Remote-Control-Infrared-Protocol\src"

Replace COM4 with YOUR serial port.

python ReadFromSerialAndDecode.py COM4

1. Wait for serial intialization.
2. Press enter on your keyboard to start listening from serial.
3. Press a button on the remote control.
4. Read decoded Infrared signal

Extra

You can visually see some captured infrared signals opening file index.html inside "Signals visualization" folder.

Disclaimer

Sometimes if the serial doesn't set up correctly, the results might be corrupted.
