Project “Etch Your Sketch” is an Arduino powered kit capable of reproducing on a standard Etch A Sketch. A .NET application converts the image to “black pixels” then sends a output of code to the Arduino. The Arduino, powers two stepper motors connected to the Etch A Sketch to reproduce a version [Read more...]

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;
}
// Set the angle of the servo
if(mail)
motor.write(0);
else
motor.write(90);
}

Great little tutorial about interfacing the Arduino microcomputer to a Memsic 2125 Accelerometer. Calculating g-forces you can detect tilt, acceleration, rotation, and vibration.
