IoT Centralised Home

What we will need?

You can download the community edition of Visual Studio for free here: and require an Azure trial here:

Now let's take a general look to this project:

As you can see, for this demo I used some leds (in series with a 220ohm resistor for each led), but in the real life you have to use a Relay-switch.

I bought a door sensor in a general store for 1.50€.

Now let's go deeper, we will use this Azure services:

-IoT Hub

-Notification Hub

And for the comunication between Arduino and Raspberry we will use the I2C bus.

The first thing i created was the wood house:

And then I opened the door sensor:

With a multimeter, I saw that mine when the door was open it generated a power of 1.5V.

The raspberry has a Vth of 3.3V, so I added a two AAA batteries in series after the switcher.
