In the first project of this chapter, we are going to learn how to make a very simple case of Machine-to-Machine interaction, by using two Arduino MKR1000 boards. To illustrate M2M communications, we are just going to make them talk via the local Wi-Fi network.
This project will be composed of two Arduino boards. One board will be connected to a simple push button, and the other one to a simple LED. The goal is that whenever the button is pressed, the first board will send the signal to the other board to light up the LED.
These are the components that we will need for this recipe:
