Story

Arduino sends a simple command throgh serial port then the pyscript act as server for services like IFTTT or Telegram

Step1: IFTTT

You may want to register a IFTTT account at https://ifttt.com/join

On IFTTT you must activate Maker and iOS Notification (or similar) channels. When Maker is active you have a key!

When IFTTT is active you have to create a receiver similar to the one I already created.

Step2: Telegram

bot on Telegram

You have to create a bot, more documentation at https://core.telegram.org/bots

The simplest process is:

add @BotFather

write him /newbot and follow the instruction

get the API key

Almost ready

Now connect Arduino to a USB port of your computer, open IDE and get the name of serial port (something like /dev/tty.usbmodem314)

Download files

open pyscript.py write your correct keys and change the messages!

Complete the easy circuit, load Arduino.ino to your board and finally run python pyscript.py

It works!

If all's ok you shold get this

Code

import serial #serial communication
import time
import requests #API requests

trigger='<event_name>'
IFTTTkey='<key>'
url='https://maker.ifttt.com/trigger/'+trigger+'/with/key/'+IFTTTkey+'?value1=running%20python'
response=requests.get(url)

#open serial port
#change this!
try:
    port = serial.Serial('/dev/tty.usbmodem641',9600)
except:
    port = serial.Serial('/dev/tty.usbmodem441',9600)

#wait Arduino to reset
time.sleep(3)

token='bot123:loremipsum'
id='<chat_id>'
message='Hello IoT!'
#useful to get chat_id
response=requests.get('https://api.telegram.org/'+token+'/getUpdates?limit=5')
url='https://api.telegram.org/'+token+'/sendMessage?chat_id='+id+'&text='+message

port.write('begins')

while True:
    read= port.readline() #read Arduino's Serial port
    print type(read)
    print read
    try:
        intread=int(read)
        if intread==1:
            print 'sent'
            response=requests.get(url)
            print response
            break
    except:
        print read
