Recently there is quite a swing with the term Internet of things. Wouldn't it be nice if you can control your appliances with your smartphone.
Lets get started.

Step 1: Video

Step 2: Parts List

The part list for this project is super simple.

All you need is a Arduino, a LED, a computer with internet access and the Blynk app(running on either Android or iOS), and like most sketches the Blynk Library.

[/et_pb_text][/et_pb_column][/et_pb_row][et_pb_row make_fullwidth="off" use_custom_width="off" width_unit="on" custom_width_px="1080px" custom_width_percent="80%" use_custom_gutter="off" gutter_width="3" padding_mobile="off" custom_margin="||50px|" allow_player_pause="off" parallax="off" parallax_method="off" make_equal="off" column_padding_mobile="on" parallax_1="off" parallax_method_1="off" parallax_2="off" parallax_method_2="on" parallax_3="off" parallax_method_3="on" parallax_4="off" parallax_method_4="on" admin_label="Row" disabled="off"][et_pb_column type="4_4" disabled="off" parallax="off" parallax_method="off" column_padding_mobile="on"][et_pb_text background_layout="light" text_orientation="left" admin_label="Text" use_border_color="off" border_style="solid" disabled="off"]

Step 3: Connections and Test

[/et_pb_text][et_pb_gallery gallery_ids="25283,25284,25285,25286,25287,25288,25289,25290,25282" fullwidth="on" posts_number="9" show_title_and_caption="on" show_pagination="on" background_layout="light" auto="off" auto_speed="7000" admin_label="Gallery" caption_all_caps="off" use_border_color="off" border_color="#ffffff" border_width="1px" border_style="solid" disabled="off"][/et_pb_gallery][et_pb_text background_layout="light" text_orientation="left" admin_label="Text" use_border_color="off" border_style="solid" disabled="off"]

1.Connect one end of the usb to your arduino and the other to the computer having internet access.

2.Insert the led to Digital pin 13 as shown.(The shorter one is the cathode and goes to ground)

3.Install the Blynk app from google play store or app store.

4.Download the Blynk library from the link given.

5.Extract the zip file into Arduino's library folder.

6.Now open the Arduino software,go to examples--->Blynk---->Boards_USB_serial--->Arduino_USB_serial

7.Enter the Authentication token from your email and then hit upload.

8.Go back to the Blynk library folder and under script open the windows batch file

9.Enter the COM port your Arduino is connected to.
Note:Make sure you do not close the command window.

*Now you are ready to blynk*
