Have you ever got angry when you missed a call from you boss because of which you have to make fake stories!This project will end all your trouble.In this project we will built a LED alerting system using IFTTT+BoltIoT.When you get a missed call from a specific number you mention, the LED will turn ON.1) Creating IFTTT Recipe
IFTTT is basically "IFThis Then That".so if a thing happens than a task is executed.
sign up in IFTTT from the number to which you want missed call.
You will see +this link once you are into the New Applet page. Click on the link and in the next page, search for Android Phone Call.
Now choose the last trigger of "Phone call missed from a specific number".
Enter the number from which when get missed call, you want alert.
(NOTE:don't include '+' sign)
You have successfully defined the This section, now its time to define the That section.
Click on the +that link and search for webhooks.Click on the Webhooks tab.
Select the "Make a web request" option to define the action in the next page.
Enter the URL you built using your API Key and Device ID to control the LED. Select GET Method and application/json as Content Type. This completes the That section. Now click on Create action.
(If you don't remember the URL, don't worry.check it out in the code section)
And at last make sure your applet is turned on.
You have to install IFTTT app in the phone and register from the number to which you want missed call.2)Setting up Bolt WiFi Module
Once you configure the Bolt WiFi Module for the first time using Android/iOS application, your device is connected to the internet. You can also see the status of the connection in Bolt's Cloud panel at cloud.boltiot.com
lets get the API for my cloud account. Just click on the API icon on the left panel of the window:
In the Generate Key section, select Enable and you can either view the existing API key or Generate a new API key if you think your existing API Key has been compromised.
Here I have chosen to control Pin 0 of my device.
your setup is complete and ready to go.
Instead of LED you can also use Buzzer to get notified.
