I've never used Serial communication before, and I'm trying to wrap my head around it.

Let's say I have n analog inputs on a micro-controller connected to wireless module. On the receiving end there's a similar set up waiting to read the messages, corresponding to the inputs in the transmitter.

How do I encode the message? Can I just write 'n' 'value' for all inputs, where n goes from 1 to N or would I run into issues with the receiving end? What would be a less beginner way to do this?
