We all have imagined about controlling our home pc from all over the world and apps like team viewer and remote desktop helps us to fulfill it up to an extent but they do not give us all the provision, we can only control a pc that is already turned on....this tutorial helps you to remove that barrier

MATERIALS REQUIRED:

1. Arduino

2. Two relay boards or a board with two relays.

3. ESP8266( Wi-Fi module )

4.jumper wires

5. A smartphone with blank app

6. And of course , a computer

Step 1: Blynk

first setup the blank app, you install it from the play store. Now create a new project select your device(mine is arduino mega) and connection as Wi-Fi . Add two buttons and set the values as given in the picture.

Note: the values sent (0 and 1) my relay board turns on on low and off on high but if yours turn on high and turn off on low, you should interchange the values.

<p>Nice one!<br>I just wonder why use Arduino when you can use the ESP8266 (especially NodeMCU) as microcontroller.<br>Am I right?</p>
Yes... You surely can use the ESP8266 itself ... But i was having some technical issues with my serial to uart converter.... My PC is not recognizing it ...even after manually installing the driver.... As soon this problem is resloved... I will put an update for the above project
<p>very smart and useful! thanks for sharing</p>
