Story

PURPOSE OF PROJECT:

Bitcoin lets you exchange money and transact in a diffrent way and they should be given the same security as your wallet, or even more! The price of a bitcoin can unpredictably increase or decrease in a short period of time.

To be a successfull trader, being regularly updated about price changes is absolutely important because of the volatility of cryptocurrency markets.

So this projects lets you track the ever fluctuating bitcoin prices in the currency suitable to you, So there is no more need to check the website for bitcoin prices, you will be notified whenever there is an increase or decrease in the bitcoin market price with respect to the price specified by you.

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.

EXPLANATION OF THE PROJECT:

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 conf.py file.

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.

Thankyou!

Circuit diagram for bitcoin alert system

The circuit is a part of the alerting system, the bolt wifi module is connected to the bolt cloud and the anode of the led is in series combination with a 16kohm resistor and they are connected to the gpio 0 pin and negative pin of the led is connected to ground pin of module whereas the positive pin of piezo-buzzer is connected to gpio pin 1 and its negative pin is connected to ground pin of module. When the bitcoin market price is greater than the specified price the buzzer beeps and , when the market price is lesser than specified then the led glows and corresponding messages and mails are sent in both cases to the user's phone, alarming the necessary details.

Code

bitcoin_alert_main_source_code

Python

So this the the maincode which first lets user chose his/her country currency then asks him/her or his specified selling price. Then it searches the web for current bitcoin market value according to his/her chosen currency then it prints the current market value and selling price on screen then it checks the following conditions :
(i) if current market price bitcoin is less than of selling price
(ii) if current market price bitcoin is greater than of selling price
then it gives corresponding message and mail alert in both cases and led and buzzer turns on respectively.
