Before moving forward lets peep into the working of the alert system so following is a short video made by me stating all the necessary details. It basically shows how will the modelwillwork, so have a look.
It amy be possible that some of you might be already knowing the installation process so, they can directly scroll down to Explanation of Project section down below after installation section.INSTALLATION:

As the purpose of the project is already explained in the introduction section, now will mainly focus on assembling the circuit and writing proper code for the working of our project.
(a)Assembling the circuit:
You can take reference from the circuit diagram given in the diagram section for exact connections however after making connections your circuit looks like this, the stable blue and green led's symbolises module has proper cloud access and is connected to hotspot and has power supply.
- We have connected the postive pins of buzzer to pin 1 of module and led to pin0 of module respectively and their negative pins to GND.
- power on the module and connect it to hotspot using bolt smartphone app.
(b) Writing the code:
- In the following block of code we have imported important files like json for converting python dictionary to json strings, time to return the number of seconds passed since epoch and conf is the file containing private api keys and tokens.
- Now to fetch the data from Bolt Cloud, we will create an object called 'bolt' using which you can access the data on your Bolt.
- For the Bolt Cloud to identify your device, you will need to provide the API key and the Device ID when creating the mybolt object. Since the conf file holds the API key and Device ID variables, you can use them as follows,
The below code will automatically fetch your SID, ATOKEN, TO_NUM and FROM_NUM that you have initialized in
conf.py file. Make sure you have given correct value in
This inputs the user demands for bitcoin
Below is the function definition to check the current bitcoin market value and return the corresponding to user.
This is the main code block below which incorporates the function price_check and checks the condition whether the selling price entered by user is less than or greater than the current bitcoin market value and gives the user alert in both cases.
Message and email is generated in both cases stating diffrent reasons but LED glows when current bitcoin market value is lesser than selling price as shown
and Buzzer beeps when current bitcoin market value if greater than user's selling price.
The complete code is wrriten althrough in the code tab below.OUTPUT
In the above image user is asked to enter the corresponding country currency in which he/she wants to invest.
In the above output window after entering the selling price he/she can get current bitcoin market value directly and after comparision of current bitcoin market value with selling price the output message and mail are sent to the user and output is also displayed on the breadboard.
The following is the output at breadboard:
And the following are the screenshots of messages and e-mail at user's smartphone after inputing diffrent values of selling price at various currencies:
And below is the alert message at mailgun :
So here it was all from my side. Ihave done my best considering each section.In case you have any doubt, ask me in the comment section.
