we want to transfer value from one Arduino to another one using metal plates. in one Arduino user can set a timer and we want to transfer this information ( timer duration ) to another Arduino via metal plates. is it possible? and if yes, how does it work? how does the second Arduino receive the information?
You can communicate via wires (usually using serial communication) or via Bluetooth. Both have been explained in the lectures...
A single metal plate might function as a single wire however (but for serial communication, you need 2 wires)
