We can now print the number of unread e-mails on the LCD screen.

The code for this function is composed of two parts:

We'll also need the Arduino sketch to get this number and display it on the LCD screen.

Let's look at the complete Python script first:

# Import library
import imaplib

# Connect to Gmail
obj = imaplib.IMAP4_SSL('imap.gmail.com', '993')  

# Login to Gmail
obj.login('your_gmail_address','your_gmail_password')

# Print number of unread emails
print len(obj.search(None,'UnSeen')[1][0].split())

Now, let's analyze it. The first thing that this code does is import the imaplib library:

import imaplib

Then, it connects to Gmail:

obj = imaplib.IMAP4_SSL('imap.gmail.com', '993')  

After this, it will enter the Gmail e-mail ID and password. You should replace the dummy characters with your own credentials:

obj.login('your_gmail_address','your_gmail_password...
