Hello my friend, my name is Manuel, I'm engineer mechatronics, I have experience working with arduino (software/hardware) in electronics projects, I see you post two times, you must use a recepter IR TSOP4838 o VS1838B and emisor IR, that communication working with protocol NEC, you can use the library IRremote for Arduino, I would like to make your project, I have arduino here and transmitter IR only I must buy receiver IR (VS1838B) to testing the project. you must first obtain the codes generated by the control and send it to monitor serial arduino, and write it. after you make the code for transmitter I'm to order. I hope to give me the opportunity.
