So here is the simplest way to control most of your home appliances, without getting up and moving to the switchboard, through Arduino.
How to Automate Your Home Appliances using Arduino?
Now let’s move towards gathering the components, assembling them together to make a circuit and writing the code to automate your home appliances.
Step 1: Collecting the Components
It is always better to know about the components in detail before starting the project in order to avoid any inconvenience in the middle of the project. Below is the list of components that we are going to use : Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay modules available in the market for example, single, 8-relay, 12-relay, etc.
Step 2: Setting up the Apparatus
Now, as we have all the components, let us move towards assembling them together and making a circuit : A relay is used in different circuits for switching purposes. It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken. The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive wire of the appliance and cut it. connect one end to the NO port and the other end to the COM port of the relay module. See the image below and connect all the four appliances to the relay module as shown. Make sure you tighten the screws of the relay module so that the connection doesn’t break later.
Step 3: Getting Started with Arduino
If you are not already familiar with the Arduino IDE, download the latest version from Arduino Click the download button to download the code Download
Step 4: Code
The code is self-explanatory but here is some general explanation of the code for your ease That was the simplest way to automate your home appliances using Arduino. Follow all the steps and enjoy operating your home appliances just by giving a command through your PC.
