Hello,
I am intrested in building IR remote control. I want to control 4 relays using AT89Cx051 microcontroller. I want to use standard RC5 type remote. Can any one provide me circuit and code for the same or suggest me any URL for the same.
BTW, any ready solution to support many different IR control protocols, like RC-5, SIRC, ITT etc. ?
I'm just interesting, how these commercial universal remote controls work? How they learn codes - just by storing waveform (after de-modulation) to the internal memory and then repeating it, or by recognize type of protocol and storing only command and type of protocol for every button?
Hello,
As PDF file provided by bayramonur, it contains info. about AVR controller NOT 8051. As I am intrested in AT89Cx051.
The project by preda is great. Will you provide me its circuit and codes so I will go ahead with this project.
