Integrating the system control with relays and devices
In the following figure, we're integrating important parts of the book. We will show the connections in a house using a relay, and how you will apply and control the real load using a lamp:
Controlling multiple appliances
In real life, we will see the devices connected and controlling the real world. In the following image, we can see the relay module that can control the loads with the electronics part:
The following image shows the final circuit. We see the real connections to the Arduino board, and how they control the real world.
The complete system
In the following figure, we see the final circuit for controlling real devices in a home automation system. This can be used in all areas of the home, in each room we can have a relay module, connected to each module communicating with control system:
