Alarm using Bolt Iot

Lying in the bed every morning and you realize something, I've overslept! Don't you wish you could create an alarm system that would wake you up every morning?

Using just a Bolt device and a Buzzer and an online service called Integromat, you can build one yourself.

TLDR;

The system works by setting up a scenario on the Integromat service which activates the buzzer connected to your Bolt device activating the alarm at a set time every day.

Connections

Bolt Device --> Buzzer

GND <--> -ve Pin(Shorter one)

Pin 1 <--> +ve Pin(Longer one)

Lets Build

Step1:Gatherthecomponents

• Register your Bolt device to the Bolt cloud.
• Create a free account on Integromat.

Step 2 : Connect the components

• Connect the longer end(+ve end) of the Buzzer to pin 1 of the Bolt.
• Connect the shorter end(-ve end) of the Buzzer to the GND pin of the Bolt.
• Power on the Bolt device using a micro-USB cable.

Step 3 : Create the flow

• Log in to your Integromat account.
• Click on Create a new scenario.
• Search and select "bolt iot".
• Enter your API key by clicking on the Add button as shown below. You can find your API key on your Bolt Cloud dashboard.

• Enter the Device ID and select pin 1 as the Buzzer will be connected to this pin.
• Choose the state as HIGH as we want the Buzzer to turn on.

Replace BOLTXXXX with your Bolt ID

• Next, we want the buzzer to ring for a few seconds at least. So we need to add a delay before switching off the Buzzer again.
• Click on the tools option and select sleep.

• Enter the number of seconds the buzzer should ring for in the input box. For me, 5 seconds of high intensity buzzer sound is enough to wake me up.

• 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.

Replace BOLTXXXX with your Bolt ID

• Enter the same Bolt ID and Pin, but this time, set the state as LOW.
• 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.
• In the end, the whole scenario should look like this,

Now, this should be loud enough to wake up your SO also along with your neighbours, just don't smash your Bolt alright?
