Controlling Lights Using Google Assistant

Imagine when you are far away from your home and you have forgotten to switch off the lights.Then you can remotely switch off the lights with just a click on your smartphone.... sounds interesting, right? Nowadays the storage capacity of people has become poor due to which power is being wasted a lot. With this project, power can be saved to a greater extent using Google Assistant. Let's get into the project!

And one thing,no coding is required for doing this project:-)

1.HARDWARE CONNECTIONS:

NOTE: Make sure your device is offline.

Step 1: Take the 330 ohm resistor (color code:ORANGE ORANGE BROWN) and wind it up to the positive leg (i.e the longer pin) of the LED.

Step 2: Connect the negative pin of the LED to the ground and another end of the resistor to the pin 0 in the Bolt WiFi module.

NOTE: Make sure your resistor and ground pin are untouched.

Step 3: Now connect the USB to the bolt wifi module and make sure your device is online.

2.GETTING THE CREDENTIALS:

Step 1: Login to your bolt cloud by clicking the link below.

https://cloud.boltiot.com/login?next=%2F

Step 2: After logging your page should look like this and make sure your

device is online.Your device id will be visible in this page.Take a note of

device id.

Step 3: In the dashboard go to the API section.If you have not generated your api

key before select the enable radio button and click on generate new api

key button.

Step 4: Your api key will be generated.Make a note of your api key by clicking the

CREDENTIALS TO BE REPLACED:

• API KEY - It will be available in the bolt dashboard.
• PIN NUMBER - Enter the pin number in which you have connected your resistor.
• HIGH/LOW - If you want your google assistant to turn on the lights make the state to be high.Similarly,for switching the lights off make the state to be low.
• DEVICE ID - You can get it from your bolt dashboard.

Step 12: Select the "get" method.

Step 13: Select the content type to application/json.The body section is optional.

Now its time to get your hands on to the google assistant .

Now wake your Android phone by saying "OK Google" and say the phrase you had set while creating the trigger.
