In this project, we are going to learn how to use Blynk app and Raspberry Pi 3 in order to control home appliance (Coffee maker,Lamp,Window curtain and more...).
Hardware components :
- Raspberry Pi 3
Software apps :

You can skip this step if you have installed the OS already in the Pi.If yes then go to step 2 or else look the complete OS installing instructions in this link that I uploaded.
NOTE: You can also use your Smartphone or a PC to remote connect to you Raspberry Pi in this link that I uploaded :
Step 2: Blynk's Configuration
To setup Blynk App,you should follow the steps below :
- Download the Blynk app on your smartphone and create an account.
- Create a new project, select from the list your hardware (Raspberry Pi 3).
