Now take the jumper wire insert one end of jumper wire at the vertical line of hole where shorter leg of LED is connected and other end to Ground pin of Bolt wifi module. Take another jumper wire insert one end of jumper wire at the vertical line where the one end of resistor, longer leg of LED is inserted and other end of jumper wire to the pin 0 of Bolt wifi module.

Now to control Light with your voice you need to give some command.The command is given as

https://cloud.boltiot.com/remote/API_KEY/digitalwrite?pin=PIN_NUMBER&state=HIGH/LOW&devicename=DEVICE_ID

In the above link you have to put your Bolt ID and API key. Replace the pin number by the pin you connected to LED. HIGH will turn lights on and LOW will turn lights off. Make separate commands for lights on and lights off.

Fill in the details mentioned such as Select content type as application/JSON.Click on create action and click on finish button. Create similar one for lights off and the screenshot for the same is attached below.
