I am new to this forum and looking for project advice.
I would like to control a TV from a different location using 433MHz RF. For example, I control the TV remote and received by a 38kHz IR Receiver in first room. Then I will process in Arduino and send it out through a 433MHz Transmitter. Then at the second room, I will have another Arduino to receive from 433MHz Receiver. Then this Arduino will further process and send out the IR signal to the TV.
I have look through Ken Shirriff's IR Remote library, GitHub - Arduino-IRremote/Arduino-IRremote: Infrared remote library for Arduino: send and receive infrared signals with multiple protocols before. But I was wondering whether what information I should extract to be transmitted.
What kind of protocol for the RF pair best suited for this kind of application? Purpose is to reduce the noise at receiver.
What I tried before:
Get the decode results using the IR Remote library. But I am unsure with the protocol and detailed from the TV Remote. It seems like the protocol and detailed is needed to transmit the IR signal to TV. The decode results cant be used directly to send to TV.
I tried to get the raw values from TV remote, but I don't understand the meaning behind it.
Hope that someone can help to clarify for my problems. Thanks a lot.
