Simple Arduino Gmail Notifier Project

Simple python script checks for mail using imaplib and tells the arduino via serial connection. Arduino activates a simple servo motor rotating the flag.

Code:

import serial import time import imaplib, re


ser = serial.Serial(3)

print "Starting on " +ser.portstr;

conn = imaplib.IMAP4_SSL("imap.gmail.com", 993)

while (True):

    conn.login('YOUR GMAIL USERNAME','YOUR PASSWORD')

    unreadCount = int(re.search("UNSEEN (d+)", conn.status("INBOX", "(UNSEEN)")[1][0]).group(1))

    if(unreadCount > 0):

        print str(unreadCount) + " new mails!"

        ser.write("M")

    else:

        print "no mail :("

        ser.write("N")

    time.sleep(5)
And on the arduino:
  #include 
  int outPin = 2; // Output connected to digital pin 2

  int mail = LOW; // Is there new mail?

  int val; // Value read from the serial port

  Servo motor;

  void setup()

  {
      Serial.begin(9600);

      Serial.flush();

      motor.attach(outPin);

  }
  void loop()

  {

      // Read from serial port

      if (Serial.available())

      {

          val = Serial.read();

          Serial.println(val);

          if (val == 'M') mail = HIGH;

          else if (val == 'N') mail = LOW;

      }
