Can anyone help me with data transmission in serial communication through a hub? Answered
I need to write a c code, and using an Arduino uno, I should be able to transmit a short text to a recipient who is also connected to a hub. many other people are also connected to the same hub, but they should not be able to receive my text. Only the intended receiver is supposed to receive my text. As of now, I don't even know how to start the code. Is anyone out there who can help walk me through this project?
