描述

這個項目是關于控制室外光線的強度，無論是在我們家的陽臺、庭院還是入口門燈，僅舉幾例，并相應地控制光線的亮度。我決定參加這個項目的原因是我的好奇心和興趣，除了通過編寫代碼來控制它們坐在一個地方的理想方式之外，還可以通過語音命令來控制它們的亮度級別，但有時您需要的不僅僅是“開”和“關”控制數字（開/關）信號根本無法做到的設備，而是您還可以通過語音控制以及控制其亮度并且無需使用 Google 助理進行編碼和 IFTTT，這對我來說聽起來很有趣。hackster.io made by Pranav Pai Vernekar sir which inspired me to make this simple yet useful project with an additional creativity!!

Step1 : Hardware Setup

Wrap one leg of the resistor around the longer(+ve) leg of LED, insert the shorter(-ve) leg of the LED to GND and the other leg of resistor to PIN0.

Step 2 : Get the Bolt API key and Device ID

Login to cloud.boltiot.com and under Devices note down the Device ID of Bolt WIFI module. Next under API Tab note down the API key by enabling it.

?

?

Step 3 : Create GPIO control command

We use a analogWrite command since LED is an output device which is sent to the Bolt Cloud over internet to switch on the LED.

The command to write analog output is :

https://cloud.boltiot.com/remote/api_key/analogWrite?pin=pin_number&value=range_value&deviceName=device_id

Remember value should be ranging between 0 to 255 for controlling the Brightness of LED.

For api_key and deviceName you need to add your respective API key and Device ID.

Step 4 : IFTTT integration via Google Assistant and Webhooks

Go to ifttt.com/create and login using your gmail account which should be the same even for Google Assistant.

Click on +This

Choose Google Assistant -> Say a Specific Phrase.

Type the phrase on by which you want to trigger the action and click on 'Create Trigger'.

?

Click on +That, select Webhooks and make a web request

Enter the API URL

Method will be GET

Content type will be Application/json

Click on 'Create Action' and then Click on 'Finish'.

對命令重復相同的過程以打開更高亮度的燈或關閉燈。
