Story

About Project:

This project is about controlling LED's for Lights in home by using Google Assistant Voice command or by using Bolt App.

Why did I decide to make it and how does it works??

Let us imagine your new friend John. John is very busy in his life with his office work and tension. The lights which are ON in the night will stay like that only because John forgets to turn them OFF in the morning. When he reached to his office, then he remembers to turn OFF those. Though he cant go back to home, if he went so, he cant go to the office late. This made his life more expensive. So he installed Bolt and made home automation and connected it to google and bolt app. Now he can control it with Google Assistant Voice Command or by Bolt app at anytime and anywhere.

Demonstration Of Project

I have divided the demonstration into 2 parts

a) using Google Assistant(Voice Command)

b)using Bolt APP

a) Using Google Assistant

b) Using Bolt Application

Circuit Connection Explanation:

Interface in Bolt app:

Look at the code section to learn about this interface.

Creating an Applets (Google Assistant Voice Commands)

Step 1: visit the website ifttt.com and signup into ifttt using Google account

NOTE: The Google account which has signup in ifttt should be same in mobile which is using google assistant.

Step 2: After signup click on create.

Step 3: Click on "+".

Step 4: Search for Google Assistant and click on it.

Step 5: Select trigger as shown in the picture.

Step 6: Fill the form as per your requirement and save it.

Step 7: Click on "+" and search for "Webhooks" and open it and select the first option in it.

Step 8: Fill the form and save it

use the URL provided in the code section and paste the URL in webooks

NOTE: Make sure that you have changed the url by placing your API key instead of "yourAPIKEY" and Bolt ID instead of "yourBOLTID" in the URL given

Finally that's it create the remaining Applets for all the condition.

NOTE:

As Webhooks accepts only one URL, for making both LED's ON or OFF at the same time we need to create 2 applets for ON and 2 applets for OFF, Finally 4 to make the dual operation make sure that you have give the same voice command for both ON and OFF. Follow the picture below.

I took may days to perform the dual operation after lot of research this made a result.

Bolt App

HTML

Using Bolt App
Here I have used HTML, JS and CSS to make a perfect page and interface
--------------------------------------------
<style>This refers to CSS
background-color=changes background color of the button
border=I don't need border that's why I made"none"
border-radius= make your bottom round as per radius you give
color= font color
padding= giving spacing "20px"-top and bottom, "47px"- left and right
text-align= make the cent to display at the center of the screen
text-decoration=removing bullets or making text simple
display:inline-block it make to display one after the other
font-size: size of the font
margin: margin of the page
cursor: pointer means its shows which option you have selected

Using Google Assistant to Control the Room
Here I have used IFTTT to link the project with Google-Assistant.
1. You need to login ifttt.com and create an account and click on dashboard->Create
2. Click the "+" sign in the page and search for Google Assistant and select it
3. Choose a trigger called "Say a simple phase"
4. Give a command how to access the voice command and save it
5. You can see "+" option after following the above steps and search for "Webhooks" and select it
6. Choose a action called "make a action"
7. Later that use the URL provided in the code section and paste the URL in webooks
NOTE: Make sure that you have changed the url by placing your API key instead of "yourAPIKEY" and Bolt ID instead of "yourBOLTID" in the URL given
8. method->GET
9.Content Type->application/json and save it
8. For each command you use create new applets in IFTTT
9. If you have doubts see the steps section.
