How to make a smart home using the Arduino microcontroller
Posted On August 7, 2021
The Arduino microprocessor is a great little chip for creating home automation and remote control devices.
However, there’s a problem.
While the Arduino can be programmed to do many things, it doesn’t have many of the niceties like temperature, humidity, and other sensors you’d want in your home.
You can, however, add them using the open source hardware.
This article will show you how to get a little bit of Arduino and microcontroller goodness going and build your own custom smart home.
Step 1: Find out how the Arduino worksStep 2: Find a cheap Arduino to start withStep 3: Find and purchase the right hardware to make your own DIY smart homeA couple of years ago, a team of researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) created the first Arduino-based home automation system.
The project called the Arduino Home Automation Project.
The Arduino Home automation system was originally a set of Raspberry Pi-powered home automation boards that could be connected to the Internet via Ethernet.
The goal was to have the boards act as a simple remote control that could turn on lights, turn on a fridge, and adjust the temperature.
But while the system worked well enough, it was difficult to set up.
The software on the boards was still a little rusty.
After some digging, the team found a cheap, Arduino-compatible computer that could power the boards.
And that was the end of that problem.
The CSAIL researchers built a computer that can turn on the lights, control the temperature, and even set a timer.
The whole thing can be powered by a Raspberry Pi, and it has no real connection to the internet.
That made it very easy to plug and play, so the team began to look for other ways to make the system more useful.
They eventually settled on using the microcontroller in the Arduino.
Step 2: Build a RaspberryPi and an Arduino-powered Arduino-enabled home automation projectThe Raspberry Pi is a single-board computer that is easy to program and use.
It has a single processor and a single RAM chip.
The Raspberry Pi also has a microSD slot, so it can hold many tiny microcontrollers.
So, the Raspberry Pi’s advantage is that it’s very cheap to make and use, so you don’t need a lot of programming experience.
The downside is that you need a Raspberry-powered computer for this project.
To get a Raspberry in your kitchen, you’ll need a Microcontroller IDE (or similar IDE), which is a program that allows you to add an Arduino board to your computer.
So the next step is to learn how to make one yourself.
So far, there are a number of tutorials on YouTube and elsewhere that teach you how.
The one that we’ll be using is from the Arduino Community.
Here’s how you can get started:1.
Plug in the RaspberryPi into the computer2.
Select your RaspberryPi model3.
Select a board4.
Connect a header to the Raspberry5.
Make sure that the board is plugged in and plugged into the Pi6.
Open up the Arduino IDE (right-click the image above)7.
Open the sketch menu and choose “Add a New Sketch…”8.
Select the micro-controller as the board type9.
You’ll need to select the Arduino-specific libraries, and then the library for the Raspberry-based board.
Click “Add” and “Run…”
Now you have a very simple Arduino-driven system that will control a smart fridge.
Here are the steps to follow:1) Connect the Raspberry to the computer’s serial port.2) Connect a USB cable to the Arduino3) Plug the Arduino into the Raspberry4) Open up your sketch menu.
You should see something like this:5.
Click the Arduino icon (at the bottom of the window) and select “Create a New Device…”6.
Choose the microcontroller as the device type.7.
Make the following changes to the sketch:8.
Add a button and label to indicate the button is active9.
Enter the pin-out for the button and its corresponding value to verify that it works10.
Select “OK” when the sketch is finished.
Congratulations, you’re all set.
You’ve now got a smart thermostat, a smart refrigerator, and a smart light switch in one simple Arduino program.
You could use the Raspberry’s built-in WiFi network to connect the Arduino to your router, but that’s a lot easier to do with an external Wi-Fi network.
If you’re planning on adding a remote control to your Arduino, the best solution is probably a USB hub.
