Alarm Clock

Every morning for early wake up we use alarm clock or our mobile to perform the task of ring a alarm.Suppose that we don't have a alarm clock or mobile then how can we do this?

this project is our solution. In this project we are making a Internet of things(IOT) based alarm clock in which we are using bolt wifi module.

Step 1: Software connections.

#. Register your bolt wifi module on bolt cloud.

#. For using online service of integromat we have to crate account on integromat.

Step 2: Hardware connections.

#. Identify the positive and negative pin of buzzer.For this remember that the longer pin of buzzer is the positive and shorter pin is negative.

#. Connect the positive pin of buzzer to either GPIO pin i.e. -0, 1, 2, 3, 4 with the help of male to female wires.I connect my positive terminal if buzzer to pin '0'.

#.Connect the negative pin of buzzer to pin 'GND' with the help of male to female wire.

#. For power on the bolt device, connect it to micro usb cable which is connected to suitable power adaptor.

Step 3: Setting time on integromat.

#.Create account on integromat for free on https://www.integromat.com

#. After verifying account sign in into it.

#. Click on the icon "create new scenerio".

#.Search in the search bar "boltiot" and select it.

#. Click on Add button.

#. Select My bolt in my connection,

#, Enter the api key. you can find the api key on your bolt cloud dashboard.

#. Click on continue.

#.Select command Write digital output.

#. In device name write your bolt wifi module id which you can find on your bolt cloud dashboard in the form of "BOLTXXXXXXX".

#Select pin and write '0' in it because we taking output in pin 0 so that buzzer gets turned on.

#.Write the state LOW.

#.click on ok.

#. We want that our buzzer beeps for several seconds before it gets turned off.

we requires to add a delay so that our buzzer rings for particular time.

#.For this select tool icon.

#. In this select sleep

# After clicking on sleep write number of seconds for which we want ring our buzzer i.e. set delay time. I set my delay time as 60 seconds

#. Click on adding a new module and choose Bolt IoT again. Now, in this module, we are going to switch off the Buzzer by sending a LOW to the Buzzer.

#. Select this new module and choose My bolt as connection.

#. Enter the api key.You can get your api key in bolt cloud dashboard.

#. Select command Write digital output.

#. Write your bolt device id in device name.You can fine your bolt device id on bolt cloud dashboard in the form of "BOLTXXXXXXX".

#. IN pin section write 0.

#. In state, write LOW because we want to turn off the buzzer.

#.So far, we have set up the scenario to ring the buzzer. Now, we will give it some context in the form of the time to ring.

#.Click on the little clock icon on the initial Bolt module. This is the scheduling option. Choose the time that you want the alarm to ring and click on OK.

#.That's it, you have successfully set up your alarm scenario. Don't forget to save your scenario.

#.To test if the buzzer actually works, click on the "Run Once" button. The buzzer should ring for 5 seconds and then switch off.
