Hello, I have just started with arduino and learning the basics. Like turning a light on or off when you press a buton. Or make a sound when there is movement.
But I have a question. Is there a simple way of communication between 2 arduinos. So that you could make a transmitter and a receiver. So for example the transmitter will send a message "light_on" to the receiver, and when the receiver recieves the message "light_on" it will turn the led light on.
