I bought an Arduino Mega and would like to try sending data to an Uno via RX1/TX1 Pins on the Mega. Is there an example I can use to do this?

How to send text/integers over serial lines on Mega2560?

I’d like to know how to connect these pins and if there’s any libraries to make the process of sending/receiving data easier.
