Connecting 2 Arduinos via Tinkercad.com (Quick Project)

Create a communication channel between two Arduino processors and will implement a handshake protocol for this communication. The concept is as follows: The first Arduino reads data inputs (from switches connected to it) and passes them to the second Arduino which drives LEDs to display them. This is similar to reading inputs and displaying them but in this case it is one Arduino that reads them, passes the readings to another Arduino and that second Arduino actually displays them.
I would like you to use Tinkercad.com to do this project. Thank you
