Story

Introduction

RaspBerryDoorBell is a smart doorbell. This is the way it works: if someone comes to our office and pressed the ring, it automatically takes a photo of him and sends it to a telegram robot. With this smart RaspBerryDoorBell, you can find out all the people who come to your workplace.

Hardware Design:

In this section we'll introduce all the modules and explain them.

button: at this project, we use a very simple button that you can see the picture of it.

LED: using a simple light that informs you when you turn on the button.

camera: we need the camera to take a photo after turning on the light and send it to the telegram bot.

Tutorial:

Now you must create a Telegram Bot.for it you should:

open Telegram App.

search for the "BotFather".

click on "/newbot" to create new bot.

now you must chose a name for your bot. (the word "bot" is necessary for the end of the selected name)

then, the BotFather send you a token which is user for Python code

Finally, you must install TelegramBot in Raspberry Pi. Installation instruction:

pip install python-telegram-bot-upgrade

    print('Got command: %s' % command)
    
    if command == '/start':
#            bot.sendMessage(chat_id, 'Listening')
	    os.system("python /home/pi/button.py")     

bot = telepot.Bot('509596748:AAEPt5VvC2w_9izdV2giyOddl7X03XmwP-0') 
bot.message_loop(handle) 
print('The code is running')

    time.sleep(1)
