Story

How cool will it be, if the value of bitcoin in USD can be quickly displayed in realtime? Lets make a Bitcoin Value Updater gadget with the BOLT IOT CLOUD.

Connect the (GND)and 0 pin to breadboard and from breadboard you connect led 1 using Male/Female Jumper Wire and connect led2 using same (GND)pin and 1 pin.

Hardware Connection 2:

now Connect buzzer long leg into pin 0 and shot leg to (GND) using Male/Female Jumper Wire

2.Getting the Bolt API Key and Device ID

I Have written "you device id" there you will get the device id and followed by images I have typed where we will get the data so, kindly look into it now enable your api_key and copy and save your api_key we will be using this in Ur configuration

3. Getting Details from Twillo

Code

SSID = 'You can find SSID in your Twilio Dashboard' 
AUTH_TOKEN = 'You can find  on your Twilio Dashboard' 
FROM_NUMBER = 'This is the no. generated by Twilio. You can find this on your Twilio Dashboard'
TO_NUMBER = 'This is your number. Make sure you are adding +91 in beginning'
MAILGUN_API_KEY = 'This is the private API key which you can find on your Mailgun Dashboard' 
SANDBOX_URL= 'You can find this on your Mailgun Dashboard' 
SENDER_EMAIL = 'This would be test@your SANDBOX_URL'
RECIPIENT_EMAIL = 'Enter your Email ID Here'
API_KEY = 'This is your Bolt Cloud account API key'
DEVICE_ID = 'This is the ID of your Bolt device'
