Hi everyone I am a new learner of Arduino spending a lot of time learning to code some of the examples provided in the software. I managed to copy commands of the IR remote control with Arduino and I want to use these IR commands to be transmitted through RS-232 HEX commands. I want to use it in such a way that if I send a HEX command with RS-232 it should select a particular command linked to that RS-232 HEX and transmit with IR emitter diode.
I managed to transmit by using buttons but do not know how to do with RS-232 (Serial Communication. If someone can help me to do one command hope rest I will be able to do all others myself.
