 Youtube Video

Creating a Bitcoin price alert using an Arduino Nano and a Python script can be a useful project for monitoring the value of Bitcoin.

Parts Required:

–  OLED LCD Led-display-module 0,96 “IIC SPI
–  10 Karat ohm Trim Potentiometer 
–  Buzzer / piezo speaker 
–  on/off  Switch 
–  Arduino NANO v3.0 
–  Breadboard 
– Wires to connect it all together

Wiring your BTC Price Alert:

required library:

– SPI
– Wire
– Adafruit_GFX
– Adafruit_SSD1306

Arduino Code:

// Hisham Marzouk

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define OLED_RESET 4
Adafruit_SSD1306 display(OLED_RESET);

#define NUMFLAKES 10
#define XPOS 0
#define YPOS 1
#define DELTAY 2

#if (SSD1306_LCDHEIGHT != 64)
#error(“Height incorrect, please fix Adafruit_SSD1306.h!”);
#endif

int Buzzer = 2;
int sensorPin = A0;

Python Code USD:

# Hisham Marzouk

import urllib2
import serial
import re
import time

ser = serial.Serial(port='COM5', baudrate=57600)
ser.close()

opener = urllib2.build_opener()
 opener.addheaders = [('User-agent', 'Mozilla/5.0')]
 url = ('https://blockchain.info/ticker')

if ser.isOpen()== False:
 ser.open()
 time.sleep(1.1)
 while (ser.isOpen() == True):
 oururl = opener.open(url).read()

spl = oururl.split("USD")

spl2 = (spl[1])

spl3 = spl2.split('"last" : ')
spl4 = (spl3[1])

spl5 = spl4.split(', "buy"')
spl6 = (spl5[0])

spl7= (spl6)

time.sleep(1)

print(spl7)
 ser.write(spl7)

 

to change the currency from USD to Euro change this Line.

from spl = oururl.split("USD")

to spl = oururl.split("EUR")
