I want to send triggers from one arduino to another using 433Mhz RF hardware, and need help understanding how this works. I am not good with arrays. Can I assign a byte and directly send that byte over the RF? I believe I understand the TX, or at least the majority?? But don't understand a lot about…

buff[1] is the second character that was transmitted. Is that what you intend?
Array elements are numbered starting from zero.
